I have a MacBook Air, and the solid state drive was one of the reasons I chose to buy it. I love the speed and silence of the drive, and the Air feels every bit as snappy as my slightly faster (processor-wise) MacBook.
I'm considering solid state drives for both my MacBook and my old tangerine iBook, although the MacBook is contingent on higher-capacity drives falling in price. The iBook's hard drive is over ten years old and saw daily use for a number of years, plus the capacity is only 6GB. As long as I can be guaranteed it will function fine with OS 9, I'd rather upgrade that one first (although installing it will admittedly be somewhat of a pain--anyone who's replaced a hard drive on a clamshell knows about this gut-wrenching process).
