The e-Holster PDA case fits both the 770 and the N800 pretty well. I bought the leather version with belt clips a couple of years ago for use with my Zaurus SL-6000, but have tried it with both my Nokias. For the N800 I leave it in the "sunglasses case" to protect the screen from scratches, and slip the whole thing into the e-Holster case. The e-Holster system certainly...um, advertises your geekery...but it works.
