I bought one of those, it looks fine and seems as it will hold on pretty well and be a decent fit. It´ll do its job until Noreve (www.noreveusa) come out with their full leather cases.

I´ve bought 4 cases from Noreve and my parents liked mine so much that they´ve bought at least 6 more from Noreve. A little pricey, but very nice. Noreve told me there´d be a 15% coupon coming up at the end of this month, just about the time their N900 case should arrive.
