The MBA is radical! I mean, third to the birth of my first child, iPad being second, this machine is the best thing that's ever happened to me. But seriously, Apple is really pushing the bar on what a computer should be like. I believe it is downright near perfect with this thing. The MBA i light years away to anything that comes closest to it in terms of computing experience. Ridiculous battery life, noiseless fan, no heat, heavenly keys and awesomely perfect trackpad. Radical!
