i got a new lappy for christmas (thanks dad!), and i also got a Targus laptop bag -- it's really roomy, nice plain black with about 10 different pockets to store shit in. i guess you could try Ebay, cause i'm not sure where in stores you can find Targus stuff.
good luck in your search

i'm looking for a Tokidoki laptop bag (they are like $100 on ebay, i'm not paying that!!), so we're questing together.
