MBAir is best dev laptop I ever had. Its super light, plenty of power and space for most app development and within reach price wise. Also, I suggest you look up Linus's rant about how he loves Mac book air and SSD for kernel development.
I wish the MBAir had 4G/LTE built in. That (and the higher res screen, and the platform security hw) are the things I like about the Pixel.
I'm sure Apple will Retinize the MBAir in 2013 or 2014. I just don't get why LTE chipsets don't appear in any Mac products. I have a VZ MiFi and it's such a pain by comparison -- I'm fine paying $10/mo to Verizon for each mobile/etc. device I have.
