Hello. I will be doing some traveling soon and am looking for a new backpack that will accommodate my G5 and GX1 with a few lenses, 13" macbook air, and some other miscellaneous items. I currently own a TT Retro7 and an Incase Ari Marcopoulous bag...both of which I love, however neither can fit my laptop. Ideally I'm looking for something that doesn't scream "camera bag" and that is pretty subtle in looks. A few that interested me are the Incase DSLR Pro backpack and the Lowepro Transit 350 AW. The check off in the looks department and both hold the camera gear I will be carrying as well as my 13" MBA. Anyone with experience with either of these bags or have suggestions for any others to look at? Thanks in advance!
