I'm packing the 8800 case right now, and it really is pretty styling. The wrapper gets a lot of bubbles under it, which show up clearly on the screen, and the outer rubber layer can get knocked out of place by the screen fairly easily... Outside of that, it really is slim and tough. Sometimes I drop it just because I can. ;)

As for the 8700 case, it comes with two scrollwheel covers: one that's just a nub that you have to use in reverse, but the other is a more complicated mechanical assembly that mimics the scrollwheel accurately. Expect reviews for both cases up on BBCool in the near future.
