Acer Aspire S7 review: An Ultrabook worthy of the name

I'm just as tired of the "Ultrabook" label as anyone, but every now and then along comes a machine that does justice to the category. The Acer Aspire S7 is one of those machines, thanks to some clever design decisions. However, the Aspire S7 also suffers from a few problems that might well be deal-breakers depending on how finicky you are.

It's hard to complain about the Aspire S7 being thin and light -- a mere 0.48 inch thick and 2.29 pounds. Despite the ultrathin chassis, Acer still managed to pack two USB ports, an SD card slot, and a Micro-HDMI plug into the unit. And the Aspire S7 feels sturdy, thanks to an all-aluminum body and a Gorilla Glass display.

One way Acer managed to thin out the unit was by reducing the height of the keyboard. The whole keyboard is inset slightly to lower its profile, although this also means each key has a fairly short travel distance. As a result, there's very little tactile feedback when typing on the Aspire S7; it's barely a step above typing on a membrane keyboard. If you prefer a notebook with full-travel keys, this may be a big turnoff. There are no dedicated F keys, either (which I personally don't miss); you have to use the Function key, plus a number.

But many other design decisions are spot-on. The keyboard not only has adjustable backlighting, but an ambient light sensor that automatically flicks on the backlighting and adjusts the display brightness when the room lights are low. Hotkeys let you toggle off the multitouch touchpad to keep it from spuriously registering when you type (although I experienced this problem a lot less often with this model than some others I've used). Best of all, the thermal vents on the Aspire S7 are on the rear of the unit, not the sides or the bottom -- no more Roasted Lap Syndrome.
