Returning to reality for a moment.
You don't have to use a one-button mouse in a mac. In fact Apple's own mighty mouse has three buttons and a scroll wheel that goes up and down and left to right. Just plug in anything you like and off you go.
Macs are great, if a little pricey. I wouldn't be without mine.
If Sony ever want anything from Amiga, they will just buy the patents/rights and use it. I wouldn't hold my breath for any magic partnership.
