I've been using the Samsing i780 smartphone for a while now and am pretty happy with it. The only thing that's utterly useless is the screen once you go outside. Shine a little (sun)light on it and you'll be frowning for a week trying to read what's on it. I reckon it has something to do with it being a early generation touch-screen but still, you'd expect more or better from a brand like that.
Other than that it's my best phone yet.
