Hey guys, I preordered a MBA 13" 256GB 2 1/2 weeks ago, and it still isnt in stock, and it looks like it wont be in stock for a while. I planned on it being my main computer. While waiting, I was thinking about possibly changing it to a 2010 13" 256GB to save alittle money, but the thing that is keeping me from doing it is the fact that it only has 2GB of RAM opposed to the 4 in the 2011. I will be using it for email, office, itunes, and iphoto, nothing to intrusive. What do you guys think? What call would you make in my situation? Thanks for the help!!
