While I like the speed & the battery life, the interface isn't all that user friendly. Like if I'm on the phone and I press the key on the top R/side it disconnects the call. My HTC T-Bolt if you hit it would dim the screen. When I make a call I tap the contact, it opens the contact up but you have to tap it again to make a call. Setting contact icons is another disaster, I upload an icon or use a photo and it blows it up so big that its a fraction of the original photo. And the Google voice command isn't worth the time to use it. I can tell it to call John F. mobile, and it reply's "did you mean"... so I still have to manually manipulate the dam thing anyway to get it to execute my command. I don't see the option to speak a text message you have to type it out.
Like I said the speed is good, battery life is great otherwise I wouldn't own another one of these phones if you gave it to me.
