I had the Thunderbolt, as well, and also really liked the kickstand!
I'm still trying to decide if I'm going to put a case on the DNA. It's such a great looking phone, love the soft touch, and most important, to me, is the size.
HTC managed to create a large phone, with a massive 5" screen, and by tappering the edges, giving it a soft touch finish, they make it managable. Let's be honest here.... I look at my son's iPhone 5, and while I personally don't like iPhones, never had one, never will... the sleek size of the device is attractive!
Add another layer to the DNA, and I hope it doesn't become uncomfortable.
That being said... I am waiting to see what Seidio comes out with. They do manage to add only a minimum amount in size, to devices, with their cases.
