I've done some searching and all that comes up is people with messenger bags, or people with bags for hiking, carrying some type of SLR camera, riding bicycles/motorcycles, or all of the above. I just need a bag for school that can carry my 15'' MBP and also put my books in (about 2-3) with some folders and binders. The closest thing I can come up with is this timbuk 2 track day pack..but would love to know if any1 has any other suggestions, or have that timbuk2 bag and their experiences. Thanks!
