So far I'm still happy with it.
My only annoyance is, as mentioned, that the Otterbox doesn't quite clip over the front edge of the N900 now, which makes the stylus a tad harder to pull out on the rare occasion I want it.
I'm thinking of pulling it apart to see if I can file down the zcover inside tab a little so the Otterbox will fully clip into place.

I don't think I would want it in a full pouch. I have a couple alarms on it so it's nice having it directly on my belt so when they go off I can just tap the screen..
