This is probably a longshot, and I'm not sure if it is allowed in the marketplace section, but my girlfriend recently left her Powerbook behind on a US Airways flight from Minneapolis to Philadelphia (April 10). By the time she realized what happened and went back to the gate, the plane had departed for its next destination (Houston). The computer had a distinct decal on its cover and was in a black neoprene sleeve when it was lost. If anyone has any leads that might help us recover the computer, please let me know.
