I’m not the only dual OS person in the house anymore. [Eric](http://www.9to5andotherwise.com) got a Dell PC laptop from work that he’ll be bringing home with him. He still has his PowerBook for his personal stuff, including iSight for chatting with the kids and me. Does anyone know of a laptop bag that can accommodate two computers? Airlines are tight on how many carry-ons one could have so it would be ideal if he could travel with both computers in one bag.
