i picked up the Tb2 Commute XL bag... its model laptop is a 17" Powerbook and fits my THICK 17" inspiron PERfectly.

its a "messenger-inspired" bag, so it has removable waist straps thats very adequate for sturdy hold on my short commute. laptop is very well padded. lots of little compartments with zippers to store things... 2 small side pockets are extra nice.

very good bag that one is.. except shoulder strap is quite uncomfy when the plastic buckles and adjusters get in the way... definately need a shoulder pad for heavy use
