Would a 13 inch mac book pro squeeze into a medium ps1? I appreciate your help!!
Not a chance!
I have a 13" MBP also; it won't even fit in my Large PS1s. (Caveat: I suppose it could squeeze in, but the flap wouldn't sit properly and the side panels would probably be stretched; not to mention there wouldn't be room for anything else.)
I can fit my MBP as well as a larger Dell that I use for work in my Large Keep All, and I believe that both would fit easily in the Small Keep All also. And, of course, the XL PS1 will hold your laptop with room to spare.
I found the Pouch is also great as camera bag, at least for a medium sized camera
