If the Treo 600 is unavailable, I may have to look at alternatives. That would certainly include the Treo 650. It is only $100 more, if I ignore the rebate. In the past, I haven't had great luck with rebates.
The 650 does offer the following advantages:
- Better screen resolution (320x320 for the 650, compared to 160x160 for the 600)
- Bluetooth capability in the 650, which means a wireless headset will work
- Vastly improved camera on the 650, which means better pics for the blog(s)
- The 650 does have a removable (replaceable) battery
