4. Samsung Galaxy S II
As I've said before, I've never been much of a fan of Samsung's smartphone designs. They use a lot of plastic, which makes the phones very light, but they also tend to feel slippery and not very sturdy. The Galaxy S II has a much nicer feel to it. The exterior is still mostly plastic but it's textured, so it feels much better in your hand. This phone is super-thin, has a great screen, and a powerful feature set. The TouchWiz UI is pretty weak, but Samsung has minimized it to the point that the standard Android UI shines through a lot more. The Galaxy S II is also one of the phones that is most universally available worldwide.
