Jeeeez and I am sitting here waiting for the Bionic to upgrade to from my D1. Wish I knew how much longer I'd have to wait. If it is until December, I might just go for the Bionic.
I want the D3, but like you, my d1 is getting long in the legs. Don't get me wrong, its running stronger now than ever before (1.2ghz and sourcery 2.2) but its finally starting to show its age with newer apps/games.
I'm thinking I might settle for xperia play until one of these true next gen phones come out. At least I'll still have a great device to run console emulators on when I upgrade. I'm just not sure I can handle not having a physical keyboard. It'll be a good experiment to see if I get Targa or D3.
