Yeah I love my Crumpler bags too, I've got the Formal Lounge (basically the same as yours) and Brians Hottub for days when I take my Sigma 70-200 out and about.
The thing I like about them is the Crumpler bags don't look like photography bags from the outside - when I'm out and about with my laptop as well I've got the best part of 5 grand on my back....I like to stay inconspicuous if I can!
