I've had an 820 and now an 830. The touch screen on the 820 was a "capacitive" style and while some worked "okay" lots of them were pretty average. The touch screen (and everything) on the Edge 830 is MILES better.
If you prefer touchscreen, go the 830, if you prefer buttons, go the 530. They're essentially the same apart from button / touch.
