I show how to use your palm to use VNC so you can use it as a screen to control your computer. Be advised that to do it for free you need a) A serial connection and b) It is a little slow. It has about a 3 or 4 second lag time. It's still pretty nice, though. If you pay for a license (I think it's like 15 or 20 bucks) for Softick PPP instead of using MochaPPP, you can use a usb connection, which is only a 1-2 second lag.
I use palmorb to check my cpu and hd temps on long trips. It can be interfaced with LCD smartie, which will display winamp info and various other things (such as temps, with the speedfan plugin). I still like palmamp for control, since it gives you display and touchscreen controls.
