I'm ready to purchase my first mac. I was just going to buy the macbook for $1000 but my friend convinced me to get the pro for the $200 difference. I went to the apple store and love the pro but didnt buy yet, I went down the street to Best Buy and they have a Macbook Air 13" 1.6/120gb on clearence NIB for $980. I'm very intriged but I'm worried about the speed. This will be my main computer for now, I would like to buy an iMac later for the house but can't afford both right now. Opinions?
