Over the last two days I charged up my Treo 600 and plugged in my SIM three times. All three times, I removed my SIM and stuck it back into my Razr V3. I can't bring myself to use the Treo 600 for some stupid reason. It has everything that I want in a smartphone: Syncs my calendar and contacts; has a full HTML (not WML) browser; push email client; and lots of apps. It's a little big, but not too big. Weird.
