Lowepro Flipside 400AW Backpack with a laptop?

[gibsonc]

Hi,

Im looking at the Flipside 400AW because I have found a smokin' deal on amazon for it and it looks a great bag! However occasionally I wan't to carry my MBP 15" and was wondering if the pockets would accommodate it? A reviewer on amazon said that it would fit a small laptop, or as chase jarvis did with one of his bags cut a pocket to fit one in?

Thanks
Chris
