+1There is no comparison. The Tbolt is miles ahead of the D1. IMO it's a crap ton better than the DX. The only issue is battery life, and swype not working the way it used to work on the DX. I'm also really digging Sense.
I thought Sense was going to be an awful piece of bloatware, but I love it! The battery life is excellent on my TB as well compared to my D1, I can use it well over 12 hours. I finally don't have to charge it all the time!
You're saying the battery life on your TB is better than your old D1 (rooted?)? You're not in an area with 4g I assume. Still that is music to my ears.
