I got this case last night. It fits my iPad while it is in thie Otterbox Commutter case. Also, my music hard drive, cables for iPad and the HD as well as my iPad stand safely in a separate compartment. It all fits nice and snug. As a messenger bag with shoulder strap it is a great fit. There is still room for a bit of expansion, if needed. And the HD, it sits in a padded pocked.
