I got my Rev yesterday and I love it so far. I went from a Dinc to the Rev.
So far I've found the Rev to be much more responsive and fluid. The screen is great, much brighter than the Dinc or Tbolt at full brightness. I don't know where some of the reviews are coming from with their criticism.
The battery life is better than my Dinc as well. I've had it off the charger for around 8hrs and it is at 43%. This is using 4G all day to surf, download apps, made a few calls and email. I'd say moderate to heavy usage.
By the way if you didn't know, 4G is fast! I've been speedtesting and the worst result I've gotten was 7Mbps. The fastest I've clocked so far is 13Mbps at my house. I'm in southwestern CT.
Like I said, I've only had it a day, so I'll update as the days go along.
