I recieved this a Christmas gift in 2000. Even up to this day, the PDA is this ADDer's little helper. It's pretty inexpensive (40 or 50$, I think). Eventhough it is pretty basic, it has a digital recorder in it, this is what makes this PDA great. How many inexpensive PDAs w/ a recorder can you find?

I would think that the entry level Pocket PCs would be the cheapest and plus they have a color screen
you can get a pretty decent pocket PC from Tiger Direct for 145 or a Basic Dell Axim for 179

I bought a Helio yesterday (or Laser Pocket 1 as they are called here) for € 15,-

I hope this little device can help me getting through my days in a bit less chaotic manner... and if not, it's still cool because I installed a gameboy emulator on it :)
