Hey Everyone, I have a mid 2009 C2D 2.66Ghz 15" MacBook Pro with 4GB RAM. I'm looking into purchasing a new 13" i5 MacBook Air, probably the 1.7GHz. How will this compare to my current Macbook? Is the i5 that much better than the C2D and will the SSD HD help out? At this point I'm pretty much only using my computer for scholarly activities- surfing the web, research, writing papers, presentations, storing my iTunes. I do some photo editing every so often. I guess my main question is, will I be happy with the performance of the MBA? Thanks for your help.
