I was hoping to hold out out a bit longer, but I've essentially been without a phone since early July (wife knocked my OG off the kitchen counter and have since been dealing with a phone whose left side is unresponsive). With HTC holding an event today, and the Vigor not being mentioned, tells me that this thing isn't coming out anytime soon (relatively, anyway).
Having said that, I'll probably pick up a Bionic sometime this week. Between reviews, videos, and my on hands-on experience, it's a good phone, and It'll be a while before something is noticeably better. The Vigor and/or Prime/Nexus will NOT be any faster. Everything is instant on the Bionic. 4G LTE is 4G LTE.
The issues are the screen, camera, audio issue, future proofness.
Screen: I checked it out and it looks fine to me. If I get too close everything becomes blurry anyway.
Camera: Took some sample pics in the store (well lit) and it was fine. The camera isn't a big deal to me anyway, so it's not a deal breaker
Audio issue: Haven't had a chance to test it yet
Future proofness: For the near future (1 year?), this is not an issue.
After reading about HTC's poor battery performance and "cheap" plastic build quality, and Samsung's poor GPS performance and "cheap" build quality and slow software updates, the Bionic is as good a choice available at this time.
It may sound like I'm trying to convince myself (maybe I am), but when I break it down, it just makes sense.
