I mentioned earlier that I recently retired the Treo600, in favor for the unlocked GSM Treo 650.
Yes, I abandoned the North American ubiquitous CDMA cell. I never again want to be forced to use my smart phone as an expensive door stop when traveling overseas.
While I really liked the 600, the absence of native bluetooth was really annoying. The workarounds (plug adapters) were ineffective at best. The 600 VGA camera was also pretty poor. The new 650 addresses these defficiences quite nicely, I can also make short movie clips w/sound. One aspect that I've not yet solved is Bluetooth A2DP profile setup. It appears that the 650 only supports Bluetooth 1.1.
My desire is to use my Bluetake wireless headsets, but they will only work natively with Bluetooth 1.2 or a software patched Bluetooth 1.1 system. I'll simply do a bit more research and find a cheap or free solution ;)
Another aspect that I've not tried is the streaming audio from my favorite internet radio stations (ie Big-Up Radio, WKUT We Funk Radio, etc). I never had much success of using the Sprint 3G network to stream the audio on the fly without annoying buffering every 30s. I certainly don't blame the Treo 600 for these shortcomings. Hopefully the Cingular network will be much improved.
So to recap (and I'm sure that I will add more later):
- Native Bluetooth
- Improved VGA camera
- Better QWERTY keyboard
- Ability to create short movie clips
- GPRS/GSM Network
Why did I ever wait so long??
