With the graphic design you are talking about, a PDA would probably not be the best investment for you. Perhaps posting this same question in the Laptops forum will yield some better responses. They might be able to give you a good suggestion for an ultraportable tablet PC. They usually have acceptable battery life and give you many options over what a PDA would give you. Good luck!
I've been researching different products and I was wondering if anyone could help me decide what device to buy. I've been looking for a handheld device on which I can access the wireless internet and edit documents. (If anyone knows of a tablet PC in my price range, one that is inexpensive enough to make up for the extra bulk I would have to carry, I would be interested in that too.) I'd like to take college notes on it so it would need an attachable keyboard and a good battery life. I'm looking for something less than $1200, but I would be willing to consider more if the features are good enough, for instance if I could do web or graphic design on the device. Although, finding a bargain would still be the best selling point for me.
Thanks for any help!
