i have searched on the forums, and i have found messenger bags for 17", and i have found vertical bags for 13" & 15", but nothing that is for both. i have been searching online as well, and the only thing i have found that is reasonably priced is an stm bag. http://www.altrec.com/stm-bags/convertible-laptop-shoulder-bag-17-in?sku_id=814274 any other recommendations for something around that price? (60ish) and something with perhaps more colour? oh, and i do have a speck hard case on it as well. i realize that affects the dimensions, but not sure by how much. thanks!
