I am thinking about going in on a Macbook Air and I'd really appreciate some feedback. Current System -2008 Macbook -160 GB HD -2 GB RAM -2.4 GHz Intel Core 2 Duo -Snow Leopard Potential System -2010 13in Macbook Air -128 GB Flash Storage -4 GB RAM -1.8 GHz Intel Core 2 Duo I have my Macbook sold for $675 if I want to take it, which I would then use toward the purchase of my new Air. 1.) What differences in performance would I see between the two machines, if any? 2.) Do those differences warrant spending $800 (after my trade-in) for a new MBA? I am now out of college and use my computer for basic functions. Lots of work with photos, occasional audio editing, and (on very rare occasions), video projects in iMovie. My Macbook has had no problem meeting my needs. I'm just wondering if the Air would suit them better/worse/same?
