i was debating the same thing. i'm sure the vigor/tb2 will have a better screen. i am curious about the hd screen. i'm not feeling this pentile qHD, but it's ok right now. It just bothers me a bit sometimes. however, i'm sure the htc's battery will suck (like they always do). I'm not putting an extended battery on that thing as it will be huge. the only thing that i will probably regret is if the prime is good. By good to me is (gsII build quality, not like the plasticy typical sammy), hd display with superamoled plus, and good battery life. but if i really like that, i will use my wife's upgrade early next year to get that and give her my bionic. but i'm loving the bionic so far (except display).
After reading all the issues with the Bionic
o Crappy screen (which I saw in person)
o Terrible Camera
o Headset static
o Dropping 4G and requiring a battery pull to regain network connection
I've decided to wait until December and see what Santa has to offer. I'm not waiting for the next best phone in 2012, just the best phone available in December. Not saying it won't be the Bionic if the above issues are addressed. I do know the price of the Bionic will drop like a rock when either Vigor or Prime or whatever comes out. For me, my OG Droid is rooted, overclocked and running strong and I can certainly wait three months for that blazing 4G speed.
