I picked up a clear Telus gel skin for my new One. I like having my phone be a little grippier, protects the back when I set it down and being clear it doesn't hide the beautiful job HTC has done on the phone.
I'm just happy that I have the option for arrow keys on it. Coming from an iPhone4, trying to move the cursor back a character or two was a frustrating experience.
It is cool but it also sort of sucks. For my DVR there's no guide button and no way to add it. It's the button I use most and not having it on there makes the app useless.
