Now while I do like the TB I will say I dont love it......
There are things I liked more on the x, for one I did like the hard keys better, I always seem to hit one of the touch keys on the TB and screw up what I was doing.
I also liked the dialer better on the X, I thought it was easier to look up someones number or at least I could do it quicker but that might be because I came from an OG droid and it was the same (I think)
The battery lasted me much longer on the X and the extended slim battery was not even noticeable when it was on. With the extended battery on the TB I can not use a case because there is not one for it.
There is no desk dock for the TB, while the kickstand is great and would solve this problem you can not charge the phone and have it on the kickstand in landscape.
Now I do like sense over motoblur but there are a few things I would change but nothing major. One thing I would like to do is save icons, apps and settings like you can with one of the aftermarket launchers (motoblur cant do this either)
I am in a 4G area so it was an obvious choice for me to upgrade, but the loss of data is starting to bother me enough to want to switch phones.
Overall I would say I am happy but do not think I will last through my whole contract on this phone, unlike when I bought my DX and I was very happy with it and had no desire to switch I can not say that with this phone, glad I have upgrades on other lines
