At some point....you just have to realize a phone is a phone is a phone. There's always going to be better. You wait for this and that will be out a month later. Hell...I still love my Razr.
My wife's DNA is great though. Fast, crisp, smooth. Most of all...it just plain old works.
The M7 looks to be caled the HTC One and it's similar to the Droid DNA and is supposed to be available for Sprint, At&t and T-mobile...I think the HTC One (aka M7) is just HTC's answer to getting the DNA onto other carriers. It is said to offer 32GB & 64GB models with a 1.7 quad core and 4.7 inch display with 2GB ram to be compared to the DNA's 16GB model with a 1.5 quad core, 5 inch display & 2GB Ram.
Supposedly Verizon will release the Droid DNA Plus later this year which will offer 32GB & 64GB models but I do not see that happening IMO. But holding out for the HTC One (M7) doesn't make sense anymore.
I had the Rezound as well & thought highly of it...too many battery issues with it but the DNA hasn't given me any issues and has a stellar battery and I'm a data hog. I responded to another user's post about disabling apps (on non rooted devices) to conserve battery life on the DNA, check it out if you're interested.
