Targus - CityGear Netbook Case
Targus - CityGear Netbook Case - Black/Gray - TSM097US
Just grabbed one at best buy yesterday. It is big enough to fit (pretty perfectly) my iPad in the apple case, a hard drive, all my cables, my magic mouse, and my bose headphones (pretty big case) and its still pretty small. If you don't have headphones to store it will also perfectly fit the apple bluetooth keyboard, and it has a divider that seems like it was made to have the iPad in one half and the keyboard in the other.
