I would buy it if it was cheaper. I just think that 150EUROS is a hell of a lot to pay for what would essentially be for me, an OS to fiddle with. There are also no kind of developer licenses available it seems. Nothing to enourage a purchase from someone who has a PPC mac mini kicking around. It's a perfect price to get the Amiga users who have been waiting to buy this on board, but after that has happened, I don't see any "new" customers. Unless they plan to cut the price after the initial rush, but then they are going to have some unhappy early customers!
Of course, if they are only interesting in marketing morphos to those already in the know, then this doesn't matter. But I don't see it growing beyond that which is a shame.
