The touch system is pretty nice on mine too. I just got this new app that has tiny buttons and I don't have a problem clicking them on my touch screen.
Most of the time it will unlock itself when I have it in my sweater pocket and I lean against a counter. I can feel and hear it unlock so I don't have any problems with it. Occasionally it will unlock in my purse, atm I have a pretty small purse and cram alot of stuff in there, so I'm never surprised. Overall it's not a bad phone, but I do want a droid, lol. I mainly want something that I can fully customize, the voyager doesn't have much room for that.
