Apple CFO Peter Oppenheimer told us yesterday that Mac OS X Lion will make its debut on the App Store today, July 20! Apple's retail stores have already received promotional posters, as well as hard drive disks to upgrade their display computers to OS X Lion. Mac OS X Lion (and probably also the new MacBook Air) will be available at 8:30 AM eastern time, and Tech n' Cars will give you a post with the full story at around 8:33!
