Nope, I'm not abandoning my Palm Tunsten E yet, nor can I afford either the Lifedrive or the Dell Axim that I might like to replace it with. I did however, just see this article, How to Put Palm data on a Pocket PC and found it pretty informative. At some point I may be due for an upgrade and if the Pocket PC camp lures me away, I'll need to migrate lots of data.
Update: Hmm...I just did some poking around and there is one somewhat inexpensive unit that has everything I want: the Palm Zire 72 Special Edition. Just something to keep in the back of my mind.
