This bag definitely gets the job done for simple, day-to-day use.

I specifically purchased this for my girlfriend to carry her 13" macbook pro (I got the medium, and the mac is wrapped in this:  http://www.amazon.com/Incase-Lineage-Protective-Heathered-CL60027/dp/B0075ANZWS) as well as any other daily-use items.  She loves the color (Grey/Cold Blue/Tusk Grey) and the fit.

My only complaints are with the shoulder and stability straps. The shoulder strap has a pad that can slide up and down, which seems nice for versatility, but I find it a little annoying.  The stability strap doesn't seem to be as functional as my bag (Chrome metropolis).  Considering she isn't riding a bike like me, that's not such a big deal.

In conclusion, all in all, it's a great bag for normal, everyday use.
