SGH-i620 is ready for business. We had some tactile problems with the touch-sensitive buttons up top, but the scroll wheel is like butter. Like most keyboards, we need some more time with it to give it a fair rating, but at first touch it's certainly passable. The screen seems awkwardly tiny compared to most recent smartphones, but it's certainly sharp and bright. In all the phone is a pleasure to hold and quite small enough to pocket, but we're not quite sure how much we could get done with it -- other than the usual photo snapping that Samsung phones are known for.
