I have a 2010 13" 1.86/4/128 and have been following the board closely ever since they released the new MBA. After reading some of the issues the new MBA owners are having - overheating, wake up/boot up times being slow compared to older MBAs (it could be a Lion vs Snow Leopard thing), I feel really good about my purchase from earlier this year. My MBA still runs the way it did on the first day - takes 13-14 seconds to boot up and 2-3 seconds to shut down. All apps open and close amazingly fast. It is funny, I am liking my 2010 MBA even more now since the new MBAs were released. Anybody else feel the same way? Anybody considering upgrading to the newer models?
