Hey everyone, I've been trying to find a decent looking Messenger type laptop bag for the 15 inch retina MBP. The current bag I have now comes from an old Dell and barely protects my laptop at all. I've seen some people with messenger type bags that protect the laptop really well and hold a bunch of stuff too. Something like this : http://store.apple.com/us/product/H0617LL/A I'd prefer a good build quality too. Preferably with a dedicated ipad (ipad 4, not the mini) slot too. The nicest one I found is http://store.apple.com/us/product/H...k-air?fnode=50&fs=m.tsFormFactor=messengerbag but it's only for a 13 inch MBP, not 15 inch. Any suggestions or recommendations?
