On the one hand, I really can't believe HTC would do this, but then again, they're really only selling QWERTY phones on T-Mobile and Sprint these days, and who knows how many units they're selling. Moto has that locked up on Verizon with the Droid, and AT&T doesn't (as far as I know) have any HTC QWERTY phones.
On the other hand, the MT4GS has a very 'meh' keyboard. Coming from the MT3GS, I was shocked at how bad the 4G Slide was in comparison to it's predecessor. I got used to it, but I still prefer the old model.
