There's a youtube video of it too if you're interested. This is the best video I've found, but there are a couple of others as well. http://www.youtube.com/watch?v=lk28LFQX4NY

It looks pretty nice. I thought to combine a screen protector since the case is open screen. There was a review of a PDair aluminum case for the playstation portable, and the review was excellent, I can't find the link to that review now though. The one for the N900 should be the same quality.

By the way, I'm very interested in this case because, first and foremost, the belt clip looks sturdy and secure. I bought a leather case from T-Mobile that had everything I was looking for (non-magnetic buckles and soft interior for the N900 screen) except the belt clip was designed like the sketch below on the left (no distal hook to catch onto your belt or pants), and it took almost no force at all to make the whole case slip right off your hip. The PDair aluminum case has a belt clip that, from what I can tell, is like the sketch below on the right, and that hook at the end keeps the case from being easily pulled off your hip or belt.
