Dell XPS 15

The new XPS 15 (also called the XPS L501X) is a completely redesigned multimedia notebook from Dell. Sporting a JBL sound-system with subwoofer, NVIDIA GT420M dedicated graphics, and an Intel Core i5 processor, this system is designed with performance and entertainment in mind. In this review, we take an in-depth look at the new XPS and see how it stacks up against the competition.

Our Dell XPS 15 Specifications:
  • Intel Core i5 460M Processor (3MB cache, 2.53GHz)
  • 15.6-inch 1366 x 768 glossy display with LED backlighting
  • NVIDIA GeForce GT420M with 1GB DDR3
  • Windows 7 Home Premium (64-bit)
  • 6GB DDR3 memory
  • 500GB 7200rpm HDD (Seagate Momentus 7200.4)
  • Realtek gigabit ethernet and Intel 1000 802.11b/g/n wireless
  • Bluetooth 3.0
  • 6-cell Li-ion battery (56Wh)
  • Dimensions: 15 x 10.4 x 1.3-1.5-inches
  • Weight: 6.21lbs
  • MSRP: $899.99 (Closest configuration)
Build and Design
The new Dell XPS 15 has a silver on grey color scheme, using metal panels and plastic for the body. Compared to past XPS designs that were trend setters that distinguished themselves from the lower models, the new XPS doesnt seem to spark much visual interest. In theory, mixing alloy panels with a brushed metal palmrest and backlit keyboard usually yields good results. The redesigned XPS 15 doesnt seem to really set itself apart, though, from the standard Inspiron 15R until you take a much closer look. Standing back five feet, the panels look like average plastic on the exterior, and the body itself even seems more bloated than the 15R. Overall, it seems like Dell missed a big opportunity to make the XPS-series the unique notebooks they once were. The result is a rather bland looking multimedia notebook where its budget-oriented sibling --the Inspiron 15R--outshines it.

Nevertheless, the XPS 15 feels nicer than it looks. The metal panels on the interior and exterior add strength to the body, reduce flex, and give the notebook a high-quality feel. Holding the notebook for the first time is a weird experience, as most of the panels look like plastic until you feel the cold metal. The screen cover does a very good job at protecting the display from impacts and seems to resist flexing when opening the screen from one of the front corners. The inside of the notebook features a large brushed metal panel that makes up the palmrest and keyboard surround. The bottom of the notebook is completely plastic (including the access panel) but still resists flex and feels durable. The only problem we noticed was the high use of plastic clips holding most of the notebook together (in addition to metal screws).

Users looking to upgrade the Dell XPS 15 will find it easy or not so easy, depending on which components they are looking to swap out. The single access panel on the bottom of the notebook houses the two sticks of RAM, wireless card, and WWAN/TV tuner slot. To get at the hard drive, you must fully disassemble the notebook, which isnt a task for the faint hearted. We counted about 16 screws, but didnt want to go further and risk breaking plastic clips or gouging the trim around the perimeter. Thats an awful amount of work just to swap out a hard drive for a full-sized notebook.

Review of Dell Mini 9

Full review of Dell Mini 9

Dell was actually quite slow in catching up with the netbook craze, and it took until late last year for the Irish manufacturer to release this model.

The Dell Mini 9 sums up everything you expect from an average netbook; it comes with the standard 1.6GHz Atom N270 processor, Intel GMA950 graphics and a choice of a small solid state drive or more roomy hard drive. Moreover you get to choose from either Linux (Ubuntu) or Windows XP Home as the primary operating system.

So, why should you buy the Dell Mini instead of one of the other myriad netbooks out there with the exact same specs? For one thing the starting price is very low, just $249, but that gets you a mere 4GB SSD, so most potential buyers will probably add a few bucks for more storage space. Nonetheless, it is still very affordable.

Another great thing about the Mini 9 is that you can get it in a variety of colors and decorations, although this will also cost you extra as per Dells business model. The standard color is glossy black (and it is very glossy I might add). The screen on the Mini is good, and doesnt have that large frame that many other netbooks have. On the downside, the keyboard feels more cramped than average, but that comes as no surprise on a 9-inch netbook.

Performance and Conclusion

The battery lasted just over 3 hours, which is completely acceptable. For some reason we couldnt get WorldBench to run on the Dell Mini, but the WPrime 32M test finished in 124 seconds.

If you feel like buying a low-end version and upgrade it later (with cheaper parts) you will be happy to learn that its very easy to access the internal components, as they are grouped together beneath a panel next to the battery.

If youre looking for a netbook, the Mini 9 should definitely be taken into consideration - its a solid, highly customizable little laptop available at a very attractive price point.

Edit: Although it would be amazing if the Mini indeed came with a 2.6GHz Atom, it was of course supposed to read 1.6GHz. Thanks Usman for the bump.

Dell Mini 9 Technical Specifications
  • Processor Atom N270 1.6GHz
  • Memory 512MB-1GB
  • Harddrive 4GB-64GB
  • OS Linux (Ubuntu)/Windows XP Home
  • Weight 2.3lbs
  • Screen 9
  • Screen resolution 1024x600
  • Graphic Card Intel GMA950
  • Battery Life 3:07

Dell Latitude XT2

The Latitude XT2 is Dells multitouch-enabled business convertible-notebook that now includes Windows 7. The XT2 starts at $1,909 and offers a very thin and lightweight business-rugged chassis with an attractive brushed-metal finish. In this review we find out if the XT2s system performance or multitouch support has improved under Windows 7.

Dell Latitude XT2 features the following specifications:

  • Intel Core 2 Duo SU9400 1.4GHz (800MHz FSB, 3MB L2 Cache)
  • Microsoft Windows 7 (64-bit)
  • 12.1" Premium WXGA (1280 x 800) LED-Backlight Display with 2-finger Multi-touch
  • Intel X4500MHD Integrated Graphics
  • 3GB DDR3 1066MHz RAM (2GB + 1GB)
  • 120GB Toshiba 1.8" 5400RPM HDD
  • 8X CD / DVD Burner (Dual Layer DVD+/-R Drive) through docking station
  • Dell Wireless 1510 A/G/N, Bluetooth, and 1Gb Ethernet
  • 6-Cell 42WHr Battery
  • Limited 3-year standard parts and labor warranty with on-site service
  • Dimensions: 11.7 x 8.7 x 1.1"
  • Weight: 3lbs 13.6oz
  • Price as configured: $2,830 ($2,262 Street)

Build and Design

The Dell Latitude XT2 has a very professional or industrial appearance with an all dark-grey design, sharp lines and edges, and even exposed screws. This notebook is definitely not targeted towards those looking for the next designer laptop. Instead, it is aimed squarely at those who just want to get down to business. The brushed metal surfaces are actually specially painted covers that give the look of metal but with the ease of maintenance that paint gives. The finish resists smudges and is much easier to wipe clean than most brushed metal exteriors. If it was painted matte black and had a Lenovo logo printed on it, you would swear it was a ThinkPad.

I personally love the side profile of the Latitude XT2, which is almost perfectly square at all corners. It has no sloped surfaces, no rounded sides, and sits very low to the desk surface. If you are carrying the tablet around in one arm it takes up such a small amount of space that you really dont mind holding it.

Build quality is excellent, and probably the best construction I have ever seen on a Dell notebook. Panels feel solid with very little creaking or squeaking plastic, and fit and finish are impeccable. Surfaces meet with clean lines and nothing feels out of place. Paint quality is great on every part of the body, with no specs of dust, unpainted edges, or any type of imperfection. The screen hinge is tough and rugged ... giving you the sense that it should hold up well over time. The chassis feels very durable with barely a hint of flex if you squeeze the palmrest or put heavy pressure on the keyboard. The screen lid has some minor wiggle, but the screen doesnt show any signs of color distortion unless you really try to twist the panel

Access to user-serviceable components is easy through two areas. The hard drive is located underneath the battery and has four screws and a frame holding it in place. The RAM, Wi-Fi card, and WWAN card are located under a single access panel held in with two screws. Most upgrade needs can be taken care of in less than five minutes or however long it takes you to swap out a component. One interesting feature that Dell puts front and center under the access panel is a user removable BIOS chip (with a handy pull tab). This lets companies replace it in the event of a failed BIOS update, instead of sending the entire machine in for repair.

Screen and Speakers

The 12.1" screen on the Dell Latitude XT2 looks great and is one of the better tablet screens I have seen in person. With the multiple touchscreen and pen input layers that tablets need over the actual display panel, most tablet screens look very hazy or cloudy compared to a standard notebook screen. The 1280 x 800 display on the XT2 looks slightly hazy compared to a normal display, but much nicer than the average tablet screen. One important feature of a tablet or slate screen is wide viewing angles for using the screen from multiple positions without having lots of color distortion. The display on the XT2 is above average in terms of horizontal viewing angles, but still suffers from some distortion when viewing the screen in landscape mode and pushing the screen back.

Backlight levels on this screen are about average with other business notebooks, but not as good as "sunlight readable" displays. Dell does offer a brighter panel for daylight use ... which should hopefully be bright enough to not be washed out in direct sunlight.

The Dell XT2 includes a capacitive touch-screen with a built-in digitizer for pen input. The pen gives excellent traction and feedback on the screen similar to a ball-point pen over a glossy hard cover book. The texture allows precise movement, and it stays consistent across the entire screen. Oils from my fingers touching the screen didnt seem to affect the pen traction too much, although for the best writing surface possible I would suggest taking a microfiber cloth to the screen first. The pen includes two side-mounted buttons for the second mouse click and erase functions. I found them to both work well but the second mouse button is slightly too sensitive ... activating with the slightest touch.


The XT2 supports two-finger multitouch with its capacitive touch display. We didnt see much improvement between the multitouch environment in Windows Vista compared to Windows 7. Scrolling and zooming in Internet Explorer 8 still feels choppy, which makes it very easy to overshoot your intended mark. Switching to other web browsers didnt seem to help much and Googles Chrome only interacted with the zoom feature. I feel when it comes to multitouch Apples hardware and software support is by far the best. Dell also didnt include any OEM-specific touch software on our Latitude XT2 besides ControlPoint which felt out-dated and redundant compared to Windows 7s own controls.

The audio system on the XT2 consists of a single mono speaker located on the left side of the chassis. It works well enough for listening to the occasional song or movie, but it sounds really off-center because the single speaker is located on one side. Peak volume is pretty loud, but it also distorts when it tries to produce bass or midrange audio. Headphones are a must.

Keyboard and Touchpad

The XT2 keyboard looks and feels great with slim keys and high visibility labeling. The layout is easy to follow with full-size primary keys and appropriately sized function keys. Compared to other notebooks the keys have a shallower throw, which is a side effect of the thin chassis. I actually found the keyboard to be quicker to type on compared to the ThinkPad X200, since the shorter throw means less travel before a key activates. The individual keys have no wiggle when you try to move the top of the key side to side.

The touchpad is an ALPS model running proprietary Dell software. Compared to the average Snypatics model it does show some minor lag, but it still feels responsive and easy to use. I think Dell could have gone with a larger touchpad surface, since the XT2 has enough space to incorporate it if you move the buttons more towards the lower edge of the palmrest. Dell also includes a pointing stick, which worked, but doesnt feel as fluid or responsive as other alternatives I have used.

Ports and Features

Port selection is excellent ... even when compared to larger notebooks. The Latitude XT2 offers two USB ports, one eSATA/USB combo, audio in/out, FireWire, VGA, LAN, and a proprietary power socket for some Dell accessories. If you need more ports or an optical drive, the docking station gives you four USB ports, serial, DVI, VGA, LAN, headphone out, and of course an optical drive. The docking station feels extremely well built, and has one of the nicest latching mechanisms I have seen. It has a sturdy metal latch arm, which when extended and released has a delayed motion where everything slowly clicks into place.

Left: Pen holder, one USB, FireWire, speaker


Right: Wireless On/Off, Wi-Fi Catcher, USB/eSATA combo, SD-card slot, ExpressCard/54, headphone/mic, Kensington Lock slot

Performance

Compared to our previous review of the XT2 running Windows Vista, the same configuration running Windows 7 seems to have taken a performance hit. Under normal day-to-day activities the system doesnt feel up to speed even when compared to new thin and light notebooks. We feel some of this could be blamed on the 5400RPM 1.8" hard drive that is half the speed of common 2.5" 5400RPM drives. Opening up applications such as iTunes felt sluggish and lengthy boot times -- even with the standard bloatware removed- were still near one minute. This could be alleviated by configuring your XT2 with one of the SSD options, but that upgrade drives up the price. The Latitude XT2 also has the disadvantage of slower processor options compared to the Lenovo ThinkPad X200 Tablet, which negatively impacts the system performance of the XT2. Gaming performance was weak with the Intel X4500 integrated graphics, but this is true of almost all tablets on the market. HD movie playback was good for 720P and 1080P video, but multitasking in the background while watching an HD movie wouldnt be the best idea with the 1.4GHz processor.

Heat and Noise

Thermal performance of the XT2 is excellent, and the XT2stayed only mildly warm throughout most of our testing. While under a higher load during our benchmarking, system temperatures crept up slightly, but still stayed within very reasonable levels as shown below. Fan noise is minimal, and I cant actually recall the fan coming on once during the review. If it was on, it was spinning slow enough that it was barely moving any air. Overall Dell did a very good job cooling the internals of the XT2.

Battery Life

The Dell Latitude XT2 has lower power consumption under Windows 7 than it did in our previous review running Vista. In our battery test with the screen brightness set to 70%, Windows 7 on the Balanced profile, and wireless active the system stayed on for 3 hours and 59 minutes before going into standby mode. This is up from the previous 3 hours and 24 minutes we saw under the same conditions running Vista. For extended battery life Dell offers a 45Wh "slice" battery which is an external battery that attaches to the bottom of the notebook. This more than doubles the power capacity of the system but would also substantially increase its travel weight.

Conclusion

The Latitude XT2 is a good looking and well built business convertible-notebook that seems to lag behind the competition. Compared to its main rival, the Lenovo ThinkPad X200 Tablet, it uses a slower 1.8" hard drive, slower processor, and offers much less battery life unless you also use an add-on battery slice. One of the XT2s biggest flaws is the use of much slower 1.8" 5400RPM hard drives ... making the performance much slower than other top-tier business machines. Windows 7 multitouch support didnt fix the problems we had under Vista. Simple gestures such as scrolling or zooming feel jerky and make it easy to overshoot your intended mark. Sensitivity adjustments for multitouch in this situation would make a world of difference. Overall the Dell Latitude XT2 would lose many of its downsides if it included faster hard drives or processors and its price came down compared to competitors.

Pros:

  • Good looking and thin design
  • Great build quality
  • Improved battery life under Windows 7

Cons:

  • Slow 1.8" 5400RPM hard drive
  • High pricetag
