The pleasantly smooth multitouch touchpad is completely flat, with no texture at all. In my tests it was quick and responsive, and it didn't go rogue with a ton of missed clicks. As a user who swears by the mouse, I didn't feel like pulling my hair out after working with this touchpad for a while, and that's about the nicest compliment I can give a touchpad. The keyboard's keys, on the other hand, were a bit cramped, shallow, and stiff. Though responsive, they just weren't comfortable to type on.
The laptop is 802.11n Wi-Fi ready and Bluetooth enabled. The latter should enable you to find a much more comfortable keyboard to use than the built-in one. The option of adding accessories while not taking up any of the precious few USB ports is a plus.
The S406 weighs 3.7 pounds alone and 4.3 pounds with the included power adapter. The laptop measures 13.5 inches wide by 9 inches deep by 0.8 inch high. It is small enough to fit easily in a typical backpack,and yet it sports a 14-inch LED backlit display.
On our battery test, which cycles 10 minutes of video and then 10 minutes of typing, the S406 held out for exactly 6 hours.
If you're looking for more power, albeit with a bigger hit to your wallet, the Acer Aspire S5 (priced at $1399 as of July 18) may be a better fit. It has a slightly smaller screen (13.4 inches) and a 256GB SSD, which significantly boosts performance.
Overall, the Toshiba Satellite U845-S406 is a great option if you need just a little extra power for work on the go, but don't feel like shelling out cash for a desktop replacement.
