Then I found this one:
MSI WIND U160 Netbook
upto 15 hours in one charge
Now I want this to bring with everyday, includes a 10-inch LED display (1024x600), the Pine Trail's standard 1GB RAM, and and Windows 7 Starter. But you'll have to make do with a 160GB HD and an island-style keyboard, which on a netbook doesn't leave a lot of room for error. But—especially if the battery life claim holds up—you could certainly do worse for more money.
