Alrighty, here's the dilemma: I'm entering University in the Fall and have the opportunity to get a new laptop as a grad gift (Thanks mom!). The form factor/portability of the Macbook Air is very alluring to me, but I'm wondering about its performance in comparison to my current laptop. I'm currently using the mid-2008 white Macbook with 2.4 GHZ, and 2GB of 667MHZ RAM running on the GMA X3100 graphics card. Now with the Air, I'm looking at a drop in GHZ, a bump in RAM speed (is that called bus side or something?) and a better graphics card. I will be using the laptop mostly for note taking, internet browsing, and editing sports video in iMovie. Will the Air perform much better/any better than my current Macbook? Also, I'm wondering about battery life. Using my current Macbook for some light web browsing at 50% brightness, I get around 4 hours of life. I'd like to use the Air in class, so will I see better or worse results? Thanks so much!
