My first Mac was the new Airs that were released back in July. I ended up returning my 11-inch ultimate, but I just bought a different configuration at the Apple store today. i5 processor this time, with a 180GB OWC SSD on the way. As far as using a Mac goes, I haven't even scratched the surface yet, but it feels great using it. Can't wait until I have everything set up and get familiar with it.
