It's pretty rare that I have to carry the 17-inchers around these days, but the need has increased a little recently and when I do I'm not really fond of a shoulder bag. Perhaps it's an impossible, but I'm looking for a backpack that'll comfortably accomodate 16-17-inchers (specifically, Apple's old/new 17-inchers, Dell's XPS 16 and Precision M6400) with accessories, and are classy enough to wear with a suit/coat but also suited for the more casual, slobby dress that I can fall into. I have a couple of hard bags from Axio, but not only are they 'barely fit' for the 17-inch notebooks (The M6400 doesn't actually fit without a potentially worrying amount of pushing and pulling), their look is more casual, and more than once I've had friends asking me why I'm carrying a vaccum cleaner on my back I also have a regular, strap/zip-laden backpack which comfortably accomodates all the laptops, but I don't really use for anything other than my laughably rare cycling outings. Any suggestions? Thanks.
