Managed to borrow a k800i and k850i from my friends.
Basically, i find that there's no difference in camera quality,
both are equally good, but the 850i just has dedicated buttons that
lit up which is a pretty cool feature.
Interface wise, there's not much diff. but exterior wise, the out
look of the k850i is slimmer and it has a smaller camera cover =
less scratches.
