I recently stumbled upon an excellent sleeve case for the Pixi. After putting a hard case on the back of my iPod Touch, the sleeve case that I'd used for it would no longer fit. I slid a Pixi Plus in the sleeve and it fits surprisingly well, the thickness of the Pixi making up for the width of the iPod Touch. The sleeve is thin and works really well when you want to keep the phone in your pocket. A good screen protector and this sleeve make a great combination.

The $10.00 sleeve, size 36 for the iPod Touch 3rd Gen., can be found at this link: Suede Jacket.
