I found a Quicknote Notebook at Fry's Electronics for $799. It is on sale at that price till tom. You get Athlon XP 1500+ processor w/ 128mb of DDR PC2100, a 10gb HD(kinda small) , 8x DVD, modem, ethernet, 4 USB 2.0 and 1 Firewire(IEEE 1394) port, XP Home, and a 14.1" screen.
It also says that the external battery is sold seperately.
that battery could cost u a bit of money though.
