I just got my new MBP with lion but i cant use my version of ms office for mac. so i called the apple store which is a few miles from me, made an appointment brought it in with my leopard and snow leopard disks and they said cool, we dont even need your disks, took it in the back and 15 minutes lion is gone and snow leopard 10.6.8 is on board with office and word working perfectly. now i am in total synch with my mac mini running SL and office. will do lion when its more stable and i figure out a compatible word processor.
