ThinkSecret reports that U.S. owners of the original and "Gigabit Ethernet" G4 PowerBooks will be able to take part in a new pilot trade in program.
According to the rumor site, Apple will be offering $700 trade-in credit for eligible laptops towards a new 15" or 17" PowerBook from Apple.
Eligible laptops need to be in reasonable physical condition, free from LCD or other accidental damage. The program will reportedly be available through AppleCare until March 27, 2004.
Update: Apparently, this program is now in place. Readers should contact AppleCare for more details. PowerPage has specifics.
