Come on, Kronos! It was just 10 people when I wrote the comment preceding yours. This means a 10% increase of interest in the poll in a matter of minutes!!!!!1111
The scary thing is that the share of people interested in "a new PPC based Amiga" has dropped from a whopping 50% to a more humble 45% in the same number of minutes. OH NOES!

On a more serious note, Mac owners like everybody else are of course more likely to buy AmigaOS if they can... well... buy it... and install it on the PPC hardware they've already got, instead of downgrading to older, slower and more expensive hardware.
