Query: Great PDA

I think this is a great upgrade from my Zire. I've used it for photos, MP3s, Audible, DocumentsToGo, Avantgo, as well as the regular Address Book, Calendar, etc. With additional memory and expansion cards, I find I also use it much more than I did my original Zire, which I used a lot!
