The windows keys and the menu keys to the right of the right windows key are all printed, but those are the only three that are.
I've been using this board since it arrived yesterday. I think it's pretty nice to type on, but the space bar is a little stiffer than I prefer. The only key cap I could get off with my fingers was the backspace key, so I'm not sure what switch the space bar has.
Also, my trackpad doesn't work well at all. In fact, it's almost useless. I can only get it to register input when I have my finger right at the edge of the pad or by repeatedly taking my finger off and reapplying it to the pad to try to get it to move. I's not a big deal, though, since I don't plan on using it ever.
