A sad day indeed, but on the other hand; if you are in a position of having to make a choice you are taking the right one. I for one have my Amiga's not as my main machine; which is currently a Pentium Core2 Duo (Conroe) running M$ Windows. I have to, because I need it for work. The Amiga's I have are for nostalgic purposes only, although I do use them.
If however you can't spare the dough to have both, or simply don't have the space, you can't go wrong with a 20" Mac.
