I think someone could make a lot of money by creating and selling an aftermarket back/extended battery for the N900. What I would want to see in such a product:

-better integrated stand than offered by official back with multiple snap-to viewing angles. Should be steady enough for unsupported use on a desk with stylus.
-Should address the camera haze issue caused by the official back.
-Charging contact points to allow charging with a desktop cradle which would come with the product. This would greatly reduce the prevalence of micro-usb connector breakage which Nokia doesn't seem to want to officially acknowledge & address.

I would be willing to pay $80-100 for such a product. Anyone with the expertise/contacts to make it happen?
