Actually he made the leap on a MacBook Pro but this post goes into just the right amount of detail on the why and how of solid state drives for portable (and desktop) computers.
My friend Dale and I have been talking about this type of thing for a few weeks now and both of us almost pulled the trigger on it last week when Apple had things on sale. Low end MacBook Pro and SSD drive to replace either optical or HD leaving optical. It’s totally doable and the screen on the MacBook Pro is easier to read (larger dot pitch) than on the 13″ Air. I actually ordered the Mac but then chickened out at the last minute and returned it. I’m not quite ready to do this yet but I’m quite sure that solid state is the (near and far) future.
