Battery for DELL Inspiron M521R

The plethora of accessories allows for increased flexibility. The docking station adds several USB ports and an additional full-sized HDMI port. The active Wacom stylus turns the tablet into a notepad. While the pressure-sensing technology works well for drawing, the palm check feature is not quite as robust.

Tablets usually don't have replaceable batteries, so we appreciate the fact that there are two to choose from: either a small and light one with 30 Wh or the heavier model with 60 Wh. Only some convertibles come close in capacity - if you also count the battery in the dock. The large battery allows for a runtime of up to 30 hours when the tablet is used as an eReader; the 15 hours we recorded during our WLAN test are also very decent, since the Latitude 10 lasts almost for two workdays without needing a charge. The only disadvantage: the larger battery pushes the weight of the unit beyond 800 grams (1.75 pounds) - something to consider. Battery for DELL Inspiron M421R

Although the overall performance is pretty average, it is still good enough for simple office tasks. Those who do not need a top performing tablet but rather want a sturdy and secure device should definitely consider the Dell Latitude 10.

Ever since our first review of the XPS 13 in early 2012, the Dell Ultrabook has changed little in terms of looks and size. Even the late 2012 model, which upgraded the notebook to include Ivy Bridge and higher RAM options, were merely internal updates.

Dell has made yet another incremental update for the 2013 model, though this may be the most noteworthy change yet. The XPS 13 now has an option to come pre-configured with a 1080p IPS display as opposed to the 720p TN panels of its older models. FHD units begin at $1399, or $400 above the base 720p unit, and includes double the RAM (4 GB vs 8 GB) and double the SSD storage (128 GB vs. 256 GB). The low 1366 x 768 resolution of the 2012 models was one of our prime criticisms when compared to similarly sized competitors such as the Asus Zenbook UX31 and Sony Vaio VPC-Z23, but the XPS 13 is finally on equal footing against other high-end Ultrabooks in this regard.

As there have been no changes to the chassis and appearance, more information on the construction quality, input devices, and connectivity features of the XPS 13 can be seen in our previous reviews of the notebook. Instead, this quick review will focus on both the display and performance of the FHD panel and the Core i5-3337U, respectively. Is this ultrathin Dell worth another look?

Case

Similar to how the ThinkPad X1 Carbon is advertised as a 14-inch notebook in a 13.3-inch shell, the XPS 13 is advertised as a 13.3-inch Ultrabook in an 11.6-inch case. At about 1.40 kg, the Dell is a hair lighter compared to the 13.3-inch Zenbook UX32VD. The slightly smaller 13.1-inch Vaio VPC-Z23 and even thinner 13.3-inch Samsung Series 9 900X3C are still lighter, though both will cost users hundreds of dollars more. Arguably, the well-crafted XPS 13 has a more resilient feel and impression than the examples above due to its combination of carbon fiber and aluminum reinforcement. The Gorilla Glass adds yet another layer of protection for the display with the usual side effects of attracting grease and finger prints from the inherent glossiness. Thankfully, the slightly heavier weight of the Dell is more or less justified by the overall strong construction and smooth, rounded design. Battery for DELL Inspiron N4420
