Wow - 36 linear inches. My 19" (21" w/ wheels) rolling laptop case has 44 linear inches if I include the wheels. If I take off the handle on top (it's either that or the wheels), and smush the front pocket, I can get it down to 39 linear inches. Wow - I'm gonna have to think about this. My shoulder won't let me carry it, so I guess I'm going to have to find a rolling laptop case that fits this criteria.
