[maemo-users] Protective case for N900

[From: Alejandro López]

Has anybody bought one of these cases?

They look wonderful on the website, but are they really effective? Are buttons (i.e. volume, photo, power buttons, etc) still usable? Is the N900 still usable once wearing one of these? What about the size? Does it increase too much?

I received a low-quality case with my N900 and I ended up removing it as it was quite disturbing and useless, but so far my device has fallen twice and I don't want to wait until it breaks...

Thanks for any useful comment.
Alejandro.
