I really don't like that phone. I hate the feel of it, and I hate the whole interface. Big deal, it looks cool...that's about it.
and I prefer non-flip cellphones...I always have trouble flipping them open with one hand while I'm driving and trying to answer a call. Rather just pick mine up and answer. As for locking the keypad, that just becomes second nature after a while, I unlock and lock it without even thinking about it.
