Ordered the matte black case over the weekend. Got it today via USPS.
It is matte black with a strip of gloss around the rim of the display.
The plastic is a little stiffer that I expected. Not very sticky so could still slide on some surfaces, but the texture helps a lot with the grip. Also, being less sticky, it shouldn't pick up too much lint.
The cutouts are pretty good. The speaker one doesn't seem to be exactly centered (up and down) but not a problem.
The buttons are covered by the case. They are slightly raised, but not by much. They might be a little hard to find by touch. It takes a little bit of sliding you finger up and down to feel where the buttons are. Not too difficult, though. The case doesn't seem to affect the responsive of the buttons.
This YouTube video shows the Galaxy S3 version of the case which is very similar.

It feels really solid now and I don't have to worry about it sliding off anything not perfectly level.
