On the bottom side, the notebook is sealed in such a way that you can't easily get at the battery, SSD or RAM. (This is pretty typical for Ultrabooks.) That bottom surface is also where you'll find the speaker strip, which is somewhat unusual: laptop speakers are usually located in the keyboard area or around the sides.

ENGADGET: Acer Aspire S7 review (13-inch): great Ultrabook, a shame about the battery life
