Quite simple my friend. Most peoples experiences of the Amiga are very positive. With Nokia on board, more people are likely to take Amiga very much more seriously.
What would that do for the A12oo? Quite easy really, Amiga Inc will have enough money to ensure that OS4 isn't the only thing they do for 68oXo Amiga's, because they will have the cash to continue supporting the classic Amiga. After all, one of the only reasons they are doing business at all is because of the still quite strong strength that Amiga owners have.
If not, then Amiga would have been dead in the water!
It can only be a good thing my friend
