I am really loving my TBolt. I would even go so far as to say I would rather have the TBolt over the Bionic. Let me explain...
First point is the screen. I know I am going to get flamed here, but my opinion is the AMOLED+ screen looks better than a qHD pentile. No ghosting, and darn it, green is green. Not green and black checkers.
Second point is the UI. Sense is way better in my opinion than any other interface created for any other platform. The app drawer on the Bionic scrolls side to side instead of up and down. Nit picky, but I don't like it.
Third point is it is my money, not yours, purchasing my phone. So my opinion matters more to me than yours. It really is that easy.
A lot will be said about processors and benchmarks and what not. The simple fact is this phone is plenty fast for what I do with it. I have never had a problem with NetFlix, Skype, HBO Go, Angry Birds, etc not running properly nor have I experienced any lag whatsoever. That tells me that even though there are "faster" phones out there, obviously I haven't found a need from a performance perspective to upgrade. That being said I do plan to jump on the Vigor like white on rice on a paper plate with a glass of milk in a snow storm when it comes out...
I suggest going to the store and playing with one. If you like it buy it. If you don't, pass. Good luck on your decision.
