just got mine today for my dell m70.
i got a black A4L, which is the 15" large sleeve. the dimensions of the m70 fit well within the interior dimensions advertised on the a4l, but it is actually a really snug fit. so much so that i had trouble getting the zipper to close at first. once i got it zipped up, the material seemed to stretch a bit to accommodate the notebook, even with the new wire reinforcement. now i can zip it up with no trouble at all.
