PDAs do not have as much computational power as a desktop or even a laptop but there are good bang for your buck when you need a pocket computer. With that said a Smartphone can better adjust to somebody's needs.

The Sidekick is a very popular brand of PDA.
There are many places to buy cheap and expensive PDAs, used and new. One of the most popular and trusted places to buy anything cheap and used online is ebay.
