I've been using a MSI U100 (basically a clone of the ASUS) for about 6 months, and I love it! The keyboard is 95% of the size of a full-size unit and it came with a built-in webcam, 160GB hdu and I upgraded the memory for about $50.
I mainly bought it for it's small size and light weight; I schlepp it out to the mini-mancave every night to banter while smoking a stick and drinking a favorite adult beverage. Battery life with the 3 cell is about 3 hours, and I've been thinking about buying the larger 6 cell battery, but what I did is buy an extra power supply unit which I leave out in the MMC, and I also bought a wireless Logitech mouse, mainly cuz I hate the touch pad on all of these.
The MSI is available at Best Buy so you could scope out the keyboard and screen, which are both perfect for surfing the net and email and such.
