Thanks for posting that. I've been looking for a replacement to my HTC G2 but have yet to find a T-Mobile phone with an acceptable keyboard. I don't know why phone manufactures mess with the standard keyboard layout so much. Trying to code on the G2 (even just HTML) is a nightmare (it doesn't even have ..yet they include a www. key???).
The Relay's keyboard looks great. I think it's the only T-Mobile phone to have 5 rows since the long dead HTC G1.
My only concern with the Relay is that it's made by Samsung. It seems like all I ever see in Play Store reviews is how various apps crash on Samsung devices. I can't say I'm too confident in the brand.
