Hi, I am new here. I just ordered the ultimate MacBook air last night and I am trying to plan out how I should spread out the memory wisely on it with win 7. My first initial thought was to so spread them equally 128gb each. But I was wondering if there is a way to maybe put 64gb on each and leave 128gb free for both OSs to access? Will windows and Mac automatically find the free space if I partition the hard drive in three sections? This would be perfect in case I wanna access the same files on either OS.
