Very curious as to what it is makes you think these "7 million former Amiga owners never came back"...
(PS: how did you arrive at that figure and how do you know they "never came back"... did you know them personally... 
Hi,
@Franko,
I counted all them suckers and believe me there was actually 7 million and one, why 7 million and one, because he forgot to count himself when he counted all them suckers.
Did I know all of them personally?
Why heck yes, used to party with all of them every weekend. Let me tell you those guys could drink, had to install extra urinals don't you know. Had to call the plumbers every weekend to unclog the womens rest room too! don't you know, I would tell you why but you all pretty much guessed why.
