Thank you for responding. I have found you info very useful. I also have 3 more questions.
1) Can the Zire 72 access a wireless home network itself or can an accesory be bought to do this?

2) Where can I purchase an FM tuner for a Zire 72?

3) I have heard rumors about some expansion cards not working for specific pdas. Should I buy the Palm one SD cards or third party SD or MMC? (I am looking for the cheapest, reliable, and best card.)

Thank you for your time.
