Cool! What is the wifi? I have the HP Jornada 720 like the one pictured below. I love this thing. Threw away my lap top once I got it. I love the keyboard that comes as part of it and it has an on-board modem or you can connect via cable modem with a socket (CF) card but have not gotten that up and running yet.
The Jornada is the little one on top of the laptop. Closed up it is about the size of an ordinary check book, just a bit fatter and only a bit bigger than an Ipaq. Fits in my front shirt pocket. Keyboard is 70% size. Don't need a mouse - just tap the screen.
