I had a Macbook Air for several years and loved it. Easily the most reliable and best made computer I've ever owned. Replaced it with a MacBook Pro which is not nearly as good. The Air isn't quite up there with the best of the best in terms of power, memory etc but I really loved it's simple, light design and it's very easy to pop in your flight case without really noticing it. I can't say the same for my MacBook Pro which seems significantly more weighty and bulky.
