This bag is big. My new 17inch HP fits in it nicely as do about 5 or so normal sized library books and all the gear that goes with a laptop. A little on the pricey side (i picked mine up for $64 because there are others that will do the job for cheaper, but it's durable and seems to be put together in a quality way. Doesn't look like it's going to fall apart any time soon and it seems like a very secure way to carry my laptop around.
