Its a delight using the 13" with a riser, external keyboard and trackpad. Lions new features, (full screen, swiping between desktops) really helps with productivity.

What you should consider is, the 13" maxes out at 4GB of ram where the 15" maxes out at 8GB (8G upgrade is around $50 dollars from amazon).

It all depends on you, do you want a light effective machine, or a powerhouse of computer power at the expense of weight.

The memory is what's holding me back from going with the Air.

The new Macbook Pro can actually take up to 16 GB RAM (though it's not a cheap upgrade). I've personally found that memory is the single best performance enhancer for the Mac - I've got a 4 GB Macbook with SSD now, but I'd love to have 16 GB RAM in a new Macbook Pro.

Ooops. I don't know why I said the 15" maxes out at 8GB. What I meant to type was.. "My wallet maxes out at the price of 8GB's". The price on individual 8GB sticks are astronomical.

$500 for a pair is astronomical? That's what I just found on Ebay.
