I have a mid 2009 13inch MBP with the 2.53GHz and a 500gig 7200RPM drive. I also have new 11.6 inch MBA with the 120gig drive. I have to choose one to keep and one to give up. I actually love both but I find myself using the MBA exclusively and even leaving the iPad behind. LOL I have to make a choice and the iPad is already on craigslist. LOL Any suggestions?
