There's another thread like this:

Meanwhile, I just found and bought:
"NEW RUBBER HARD CASE COVER For Nokia N900 BLACK"
http://cgi.ebay.com/ws/eBayISAPI.dll...m=280409355085

It'll take 7-15 business days to arrive, so perhaps my N900 will arrive before it (whimper!), but I figured it was worth a try given the price: £2.79 GBP / $4.55 USD

The price may also mean it's less than awesome, but there's not exactly a big selection of N900 protective choices out there. I'll post when it arrives.

Oh, and I also contacted ZAGG /InvisibleShield, BodyGuardz and bestskinsever to ask if and when they'd have a N900 product. All gave "not yet, but if there's enough interest..." type answers.
