I bought the PSP case from RDS Industries for my Nokia N800 and it works perfectly. It has room for headphone and power charger and the case is cheap, good looking and not too big. Therer are 2 colors: black, blue, and grey. I like the black but it's hard to find this color. I got the last black one from Best Buy. You should check online availability first prior go to the store.

I went to Staples and got a "At a Glance" daytimer and took out the guts. Works great and has just enough room for a small note pad and both the earphones and connectivity (usb) wire and its leather.

I bought the Nintendo Black Zipper case. Room for the charger, headphones, and my MP3 player, yet not to big. Very cheap at Target for $7.
