Apple is planning a significant revamp of the Genius Bar that could both reflect a changing of the guard and improve the experience for customers, a rumor late Saturday may have uncovered. Stores will supposedly replace the MacBook Pros with iPads, 9to5 understood, using an app equivalent to the GCRM repair management tool that they use now. The swap would let Geniuses move around the store to help diagnose systems anywhere in the store.
