I have the previous version 13" MBA 1.86, 128 GB SSD, 4GB Ram. I have had Macs for years, it's easy to recommend one to a friend, but when it comes to me it takes me weeks to decide. I mainly do iTunes and internet/email. I know go MBA would be the reasonable answer, but money is not an issue. I love the Quad speeds of the Pro and may even put SSD to make up for the loss on the air. The air is amazingly light, but I lay in bed with my computer on my chest or at a desk, only time the computer travels is when I go out of state every couple weeks and carry the CPU from house to the car to the house and back, and again using at a desk or in bed. Not too much travel. But I can lift the air with my wrist can't do that with the Pro. Why I want the Pro now? Its faster, more upgradeability as far as HD, bigger AG screen, without SSD the I may miss my air, with it I'm sure it would blow the Air away. Why I want the Air still? I love the ultra portability, and lighting fast data transfer and SSD. Cheaper than what I will do to the Pro. So like I said I know about all the speed differences, just looking for some advice, I've been given a lot of "get the Pro don't be stupid" I am just not sure if I will miss the Air or if I will regret not getting the Pro? Would appreciate any feedback.
