I was just at the Apple store and the guys showed me a great comparison between the SSD and the HD. They set one of each computer next to each other, selected all the applications at once (except for Front Row and one other, Photo Booth maybe) and then opened all the applications simultaneously. All apps on the SSD MBA were completely open before 1/4 of the HD apps opened. It was insanity! I realize that opening all apps at once isn't something you need to do, but it was cool to see a direct comparison between the speeds of the two drives. Definitely try it yourself if you get the chance.
