iTouch will have a better battery span than a PDA will however there are far less applications on an iTouch than you can get with a PDA. A PDA is still more appropriate if you need it for computer functions� iTouch has more entertainment value. Touch does not support WMA files which is a music store standard. You can only play what you buy from iTunes. PDA's have the ability to play pretty much any music. The storage capacity of an iTouch smashes that of any PDA although PDAs are capatible with SD and CF memory cards so extra memory is always an option.

If you asked what a file on a PDA is, my answer is everything. anything you see on a desktop computer can also be a file on a PDA. If you asked what a .pda file (having an extension of PDA), sorry, no idea. :)
PDA's can be connected to a computer. Files can be transferred from the PDA to the computer and from the computer to the PDA. Data such as phone numbers, addresses and appointments can be synchronized between PDA's and computers so the information can be the updated.
