I have a droid x2 and I really like it. It's a big improvement from my D1 and any problems I had software wise were fixed by supercharger.
My main problem that isn't the locked bootloader or pentile screen has got to be the feel of the phone. Actually it's my problem with a lot of phones. I dislike how light it is, I dislike how light my D1 was and I dislike how the business seems to trying to go towards lighter.
I got to mess around with a TB the other day and I fell in love with how it felt. It was heavy, and the curves felt great. I actually bought a case for my X2 just because I needed it to be bigger and heavier.
I'm also turned off to phones like the GS2, that look fantastic in every department, because of how thin and light it will be.
I have an upgrade in feburary and plan to hold on to it until I find a phone that both is built like a thunderbolt and has some power to it. With the way people are wanting light phones, I'll probably be sitting on that upgrade for a while.
