I'm still rocking the Blackbook from 2006, looking to upgrade to a MBA 13", either 2011 or 2012. I only have about 40GB free on my current computer, which has 160GB HDD, so I'm thinking the 128 isn't going to be enough for me given what I've read on this board. I'm not a power user and only really use it for web, e-mail, powerpoint, etc. BH Photo has a 2011 MBA with 256GB and 2GB RAM on sale with free applecare for $949... that's pretty cheap considering the 2012 version is 1599, but has 4 GB ram. Since I think I need 256GB, not 128, is the 2GB vs. 4GB going to be a huge difference? Is there any reason whatsoever I should get the 2012 vs. 2011 if all I'm using it for is basic functions and travel computing?
