Thank Bob for HotSync
I lost my Treo 650 a few weeks ago, so this came at almost exactly the right time. I filled in with a spare Sony Ericsson handset, but I missed the proper keyboard for texting and couldn't face typing in all my contacts again. Now I've got my Centro, I don't need to... plug in to USB, press the HotSync button, and a few moments later I've got my old phone back again -- but in a sexy new package.
Can't say I would have "upgraded" had I not lost the old Treo. PalmOS badly needs UMTS/HSDPA, though the Centro is EDGE enabled, and browsing is definitely faster. Blazer isn't quite as brain-dead as before, and no longer re-fetches the entire page when you hit the back button. Why is there still no WiFi?
So, it has a nicer form factor than a Treo 6X0, a better camera, and Google maps. The price is nice too, and it's dead easy to use.
