    Has any website done a comparison of these two processors? For $90 the i7 seems like an easy choice but I want to make sure I maximize battery life as this will be used primarily at school. I've searched online and can't seem to find anything for the 2012 models.

    Does anyone know?

    I'm interested in a battery and heat comparison between the 2012 i5 and i7 too.

    The reviews are still coming out. AnandTech is usually the most thorough, but also the last to come out. Last year the difference was negligible.

    I have had an MBA '12 13" for 3 weeks now and ...

    I also had a 2011 MBA 13" for 9 months. Both were the highest spec'd processors. The 2011 model would get a bit warm and the fan was not uncommon when I was doing a CPU-intense operation. But the 2012 definitely seems cooler and quieter. I have been sitting here for about an hour web surfing and the heat is negligible if there is any at all. (I am in Colorado and it was in the 90's today.) I just unplugged it and the battery meter says 8 hours. So this is light work but I have found the battery life to be excellent.
