My current phone (Samsung Captivate) is running Android 2.2 and there is now a 2.3 upgrade available.
I am utterly happy with this phone - its only issue is that the battery seems to drain quickly, and one of the touted benefits of the upgrade is 'improved battery performance', so that, in itself may be a sufficient reason to upgrade.
Except for one thing: fear of disruption. Yes, I can back up the few critical data files, and am already syncing my personal data (especially that all-important Calendar) with Google, so why delay?
It's just 40 years of computer experience (wrote first program in 1970) that has shown again and again the profound wisdom of the "if it ain't broke..." mantra.
Anybody convinced that taking a phone from 2.2 to 2.3 is both relatively painless and absolutely worthwhile?
