Something Im wondering about the Razr is that maybe is it just a glorified TB or even a X2 just 4g and thin? Im buying the phone on ebay.
Nope. The Razr is a thin Bionic with a MUCH better screen (SAMOLED vs LCD).
The RAZR is heads and shoulders above the TB- it is more than twice as fast (better dual core vs worse single core) with a MUCH better GPU and screen. The TB was the first LTE phone, it really shouldn't be considered now unless cost is the primary decision criteria.
Compared to the X2 the Razr is thinner, has LTE, and a MUCH better screen. X2 is basically a Bionic without LTE and with a worse CPU.
The Rezound is the only decent HTC option. If you like the HTC stuff, get it over a TB. I don't outright recommend it though because it has a 720p screen using an OS not meant for it, and I know from experience that kinda sucks thanks to my Nook Color. But it will get ICS eventually. The Rezound (and the Nexus) IS the phone that will still be worth a damn in 2.5 years thanks to the 720p screen, if that is your decision criteria. Hence the extra cost.
One last thing: any of the phones, even the iPhone, is a tank in an otterbox. If you are getting that case, leave fragility out of your decision criteria.
