I read that the scroll wheel on the new classics won't work through the material on this case. I haven't been able to confirm this though, so if anyone can, please speak up.
Contour have announced (with zero pictures mind, but its going to look like the 5G) Showcase for the classic - something will be available in a month, and that's the only case for me. Every single full sized iPod I've owned has had a showcase, and my new classic will be no different - they're great cases...
The Contour Showcases are pretty good and don't add too much bulk. Worth looking at the iClear from Griffin too, they are good quality. http://www.griffintechnology.com
If you really want to go upmarket, take a look at Vaja. http://www.vajacases.com
Just looked at the Contour Showcase... wondering how much extra size it adds or if it's not that big of a deal.
