I ended up changing my mind, and going with the stock amazon case.
I'm not really liking it though. Fit is very nice, but when the cover is opened all the way against the back of the tablet, and you're holding it, the edges of the case are kind of "sharp", and dig in, at least the way I hold it.
It looks nice, but I'm not 100% sure I'd recommend it to anybody.
AT&T SGS4 stock, rooted.
