I think this makes complete sense for Adobe, new products are bought by early adopters, early adopters, are, well, early adopters, they buy new stuff, they have the latest Mac, the latest iPod, the latest this and that, these are the people that companies rely on to actually spend money on the product, review it, tell their friends about it, etc. It's just how it works, Sales 101. These early adopters all own Intel Mac's, and will have a second or maybe even third iteration Intel Mac when Soundbooth actually ships.

Ok, yea, it would be fun for the PowerPC guys to dink around with the public beta but Adobe knows when the price goes up these guys won't be opening their pocketbooks quickly.
