I've got a 13"MBP and just got a 13" MBA (but just for testing, I'm gonna return it cuz I cannot afford 2 laptops and I don't need 2 laptops) anyway, so far the MBA it has been awesome: it's lighter ( that is perfect for people like me, who like to lie in bed with the laptop, I actually never use it on a desk), it doesn't have the unnecessary Ethernet port, FireWire port even the Optical drive, which I personally never use, even the speakers are louder than the 13" MBP. However the graphics suck!!! The MBP has much much better graphics! But the thing that bothers me the most is that everything on the screen is smaller, the windows, the menus, the icons, even when I open Safari. (I mean smaller than on the MBP). Does anybody know why is that and is there any way that could be fixed, and please don't say it's because the MBA has more pixels, the iPhone 4 also has more pixels than the 3Gs, but you don't see the apps smaller.
