A classmate of mine owns an EEE, so I've seen it first hand. It's intend very small; in fact, it looks like a toy. It's about as heavy as a bag of potato chips. Despite its size, the battery only lasts about 2 hours. Smaller the laptop, smaller the battery.

With that said, for $400 this is an excellent value for a true UMPC. Build quality seems pretty decent and it has most of the functions of a regular laptop.
