I use a MacBook Air for all of my work when I'm not in the office and I love it. I could even use it as my primary dev machine at work and feel great about it. I'm very happy with my machine, which is a souped up 11 inch. The only contraint is monitor size, which is easily remedied with a large external monitor or an iPad via Air Display (http://avatron.com/apps/air-display http://avatron.com/apps/air-display). The MacBook Air honestly feels much faster than my work MBP due to the flash memory.
