The Palm TX replaces a failed Lifedrive PDA.It does everything the Lifedrive did and is more compact in the bargan. All my programs and data transfered with no problems.Subjectively, I think the TX is slightly faster.I don't miss the memo recorder as I didn't use it on the Lifedrive. However I wish the TX had an indicator ala Lifedrive to show when it is charging and when the system is playing music with the display timed out.The TX seems to be totally compatable with Vista whereas the Lifedrive had some problems in this area.All-in-all I consider the TX as an upgrade and not just a replacement.
