I bought mine from DiscountLaptops last week. 1.86Ghz, 60G 7200rpm HD, 512M RAM.The display is beautiful, it runs flawlessly. So far I'm really happy, with one exception -
A big reason for choosing this system over the others I was looking at was the advertised 4-6 hr battery life. I would have preferred the extra 3/4" vertical screen size of a 15" display, but decided battery life was more important.
After discharging/recharging the battery a couple of times I did a simple test, and let it run on battery while I watched TV.
The battery lasted almost exactly 3 hrs.

This was with the unit in "Battery Saving" mode (CPU performance 25%?), wireless card disabled, no CD/DVD activity. All I did for three hours was use a web browser with a direct ethernet connection.
I didn't expect to get what they advertise, but I was hoping to at least approach the low end of the range.
