Summary: The laptop compartment itself is spacious enough to fit additional components (about 2" total depth)j, though I would recommend putting the laptop in some sort of sheath if you choose to do this.
Pros: Clean, compact, no-frills design.
Cons: Not a whole lot of extra storage space outside of the laptop compartment itself. I can fit a wireless mouse and a portable DVD drive neatly in there, but would feel uncomforable adding anything bulky.
Pros: It really was exactly what I needed. I got this in ONE DAY! THAT WAS AWESOME! And yes, I did the normal 3-4 free shipping too. Any who, yes, this just barely fit my laptop (Y510P). It keeps it snug, which I like. Also fits my monster power adapter as well. A little space to spare too.
Cons: Nothing major, I prefer bags that let you slide the laptop in - you kind of have to lay the bag on a desk, open it up, then place you laptop. Not a big deal though.
