What kind of backpack? I need something that doesn't move around when I am going 40km/h.

Mine's several years old. I've a custom sleeve for my laptop and I was the instigator for the tumbler side pockets (so I could take my coffee to work).

I purchased it when commuting ~200km/day on my motorcycle (I'm much closer to work now and can bicycle).
It does not move around at high speeds (>100km/h) and has protected my laptop from many a downpour.
