I want to get the new MBA, but am concerned about the ssd sizes (and prices!) How big of a drive would you ideally need to dual boot? On my iMac 2011 I have enough space to do so comfortably. Would 128GB be enough to run win7 and os x? I feel 256GB to be the minimum and shared equally, but cannot afford to drop so much more cash! Anybody else got bootcamp set up on the MBA and felt ok with the space? Thanks!
