I was looking for a canvass bag to put my D90, lens, and flash for travel and some documents.  And if not camera stuff, I would want one that could fit my 13" Macbook Pro, a book and notes when I am in class.  This is perfect canvass bag for me.  Not too big.  It fits my needs as I have described only that the 13" Macbook Pro is 2 inches longer.  It would fit when the side of this bag is stretched to the limit and only the Mac is carried.  It could fit the iPad though.  I am satisfied overall.
