A few good links on the Treo 600 for future reference:
- MovieRec is a simple movie recording app for the Treo; still under construction, but I tried it out and it worked pretty well
- Jeff Ray's Treo 600 Page — lots of good software links, tips and tricks, including some hacks like changing the default carrier splash screens
- Two active Yahoo! Groups: treo and treo600 — I'm not sure which will be the better of the two lists, so I subscribed to both for now
