I am buying the 2012 MBA with 8GB of RAM and 256 SSD. Now I only need to decide whether to get the i5 or i7. I am planning to use it as my main computer. The only game I play is minecraft. Other than that I use it to browser the web, watch videos on YouTube and Netflix. I don't mind the price but what I am worried about is the fans and heat produced. Any MBA 13" i7 users can tell me how long does it take for the fans to be hearable when you browse the web? I don't mind the fans and heat when I am playing intensive games because I want to get the most out of the game. And how long does it take for the fan to quiet down after you play a game and the fan comes up? If the fans come up earlier then 90 minutes of web browsing or watching videos on youtube I'm going straight for the i5. I do not plan to upgrade it till the 2014 model comes out. Yes I know the fans are always active by saying the fans "come up" I meant when it can be quite noisy.
