I really like the iPhone, but I text a lot, and I can't imagine it working too well with that phone, can you? There'd be no feedback. I'm glad that Apple is being our saviour with the whole "These other phones have buttons that can't change" dilemma but they can provide tactile feedback for texting, which is handy. I think the SMS issue is a bigger one that the buttons being unchangeable.
Is anyone else concerned?
