I'm keeping the phone.
It works. It works well (Take5) in fact.
To be blunt, I have no reason to replace it at all.
Until the VAST majority of apps no longer work on 1.5/1.6 and there's some MAJOR improvements in hardware in general, I see no need to update to a new phone.
I figure that should be late 2012/early-mid 2013. We should have Terga (or whatever) 3D standard on most of the phones by then, as well as a lot more support for Android as a whole by software companies.
No, I don't think I'll be dropping this one any time soon.
(For the record, any time I replace a phone, the "old" one becomes the company I work for's "On Call" phone, and they subsidise a new one FOR me, so I'm not stuck with a "2-Year Upgrade" routine ;-> They currently use my old Razor >;->)
