The launcher runs fine. and looks ok,
I have gotten too used to touchwiz to like anything else,
however, this can also be used as an app i.e hitting back button does not close it.In that way it provides most of its functionality on demand and serves good for hands-free operation when needed, though s-voice did that kinda similar too.
App Drawer does not have any menus or settings so nothing much to write home about there, other than it's obviously different.
I have it set up minimally for reading stuff only (news and books) and here are screen shots.
EDIT: I just Realized that I replied to an almost amonth old post.
