AIX requires hardware AND support with high margins on both. Linux can be run on a plain jane Intel box. I don't know, maybe you're barking up the right tree, I'm often confused at IBM's decision-making, and also confused about the marketplace pushing Linux so hard, but I still highly value IBM's products.
As a shareholder I am glad to hear that.
It's really no mystery. It's about moving application software, which is where the biggest margins are. Intel hardware has been effectively commoditized, now IBM is now trying to commoditize OS as well as high-end hardware.
