I'm getting the DNA today, and one feature I really appreciate is that the DNA is ready for inductive charging, out of the box!
I think I'll LOVE having inductive charging, and having to spend $$$ to get a replacement back, and/or having to have your device larger to allow inductive charging wasn't too appealing.
I'm currently using a Razr original, and the battery life sucks. I find myself in my bedroom, with my Razr plugged in and charging at the end of the day, and the phone rings! (We got rid of our house phone about a year ago)
Now I have to unplug it, have my conversation, then plug it back in again. This happens several times throughout the evening, and frankly, is a pain!
Now... I can simply pick the phone up, talk, and when I'm done with the conversation, set it back down on the inductive charging mat!
May sound like a simply thing, but I'm glad HTC included it!
