Ok. First. Love the durability. I use this sucker for my heavy 2011 17" Mac book pro. Fits perfectly! I get a lot of compliments as well. People love this bag! I use it everyday through all weather. Ok. Here comes the bad news: The leather bottom is STAINING ALL MY PANTS! It looks like I'm rubbing my lower back on some weird brown stuff. Not cool!!! And yes. It stains. It mostly comes out after a wash, but I'll be honest - I wear my pants a couple times before I wash em. So. Woof. That's it. I love this bag 100% otherwise.
