First off, I know everyone has their own opinions and needs, but I guess I just would like a fresh perspective.... I am a teacher who uses his 2006 MacBook Pro 15 1.83 ghz everyday in my classroom. Things are starting to act up, but they are mere annoyances (WiFi takes 30-40 seconds to connects after sleep, connecting to an external projector blues out the screen for 10-20 seconds, little things etc.). I also use my iPad (1st gen) for keynotes and some class actives that support display out. I am afraid that my Pro's days are behind it, but I really like the computing power it still has if I choose to use it. Anyhow, long story short, I have the opportunity to buy an old stock MacBook Air 13'' 1.86 C2D with the 256 SSD for $600 from Best Buy. It was old stock that had just been sitting around, no owner. Should I take the plunge? What can I expect from the Air (other than the obvious no DVD drive)? thanks!
