I've been following these UPC (ultra portible PCs) very closely for quite a while. I'm still hoping for a Tiqit 83 (www.tiqit.com) because of the PC card slot. If they can get the price down, I'm confident they'll kill PDAs as we currently know them.
How is it pointless? I carry a 1" 3.5lb laptop (dell c400) in a leather slipcase because palms grew too limited for me and I couldn't find a light weight I liked at the time. If something like that had a decent keyboard or could run off a small usb keyboard they would be useful to me.
