I've had this phone for a month and its a cracker. You quickly get used to the size and I wouldn't want to go back to anything smaller. It fits into the pocket of every pair of pants I have, I don't have to squint at a tiny screen and my fat fingers hit the right key more often than not now. And I don't give a f*** about how I look making a call.
But if its too big for you there's plenty of smaller phones on the market. Choice is a good thing.
