For me, I actually think 4.65" is still a little small -- 5" would be best for me. Much to my very slight irritation, the only 5" phone currently is the Galaxy Note, which doesn't use T-Mobile US's 3G or 4G bands. I do know a few people who prefer smaller screens, but it does seem that 4" is around the sweet spot for most people.
