As a quick fix, since I am now playing quite a bit with the n800, I have modified my Logitech PSP case, and it works a charm. All that needs to be done is snip a little piece of the rubber gasget where the three top buttons are -- both on the lid and the bottom -- those pieces of rubber simply pull out.. It even doubles as a stand, and since it is plastic, has no negative impact (that I have measured) on reception of wifi. This is only a temp fix, and didn't impact the ability to hold my PSP at all, either. Now I just want to find a film to cover the screen so that I don't scratch it... probably modify a PSP screen guard as well.

P.S. On the downside the case is wider than the n800, so it makes it bulkier, but since it is held very snugly it doesn't move around at all, and can be dropped in a bad or coat pocket with no misgivings...
