now that the 13" MBA & MBP are the same price, I'm stuck thinking & haven't been able to decide between the two. my current 2008 MB struggles with 4gb & page outs a lot, so I'm looking at 8gb, I could throw 16gb in an MBP though, I don't really want to be thinking in 3 years, I wish I had 16gb. the hard drive on the MBA is tight for me, 128gb which I guess is 120 formatted, I have a extreme connected airdisk so in theory I could use that. my concern with the MBP is that it isn't as future proof as the MBA, from the keynote yesterday I noticed the MBA will gain some features in Mountain Lion the MBP doesn't, I know they are only small now but who knows what 10.9 will bring. where would you spend your money given the choice?
