A PDA will provide you with the data entry device for the
uses you mentioned. However - even on its best days - a
PDA will never be a Game Boy. The device was not really
made for games, even though it has the processing power and
display characteristics to provide some diversions. You
may want to give some additional thought about purchasing a
PDA which will be used extensively for games. (Just my
opinion here).Handspring has their Prism model on sale for $300, a $100
reduction. This might be worth a look. Then compare the
features of this to other PDAs, and make your decision.
