Classic fanboyism. I got my 2011 iMac and I was regretting my purchase every day since it has bring nothing but more and more failures until it was replaced. 5 times repairs for 1.5 years.
Funny my Pentium 4 box was fine and trouble free for 6 years, and counting.
Just as PC, Mac is not perfect.
Sheesh, I never said Macs were literally magical (because everyone already knows that ). I just said I think he'll be happier with it, not only ecause it's better, but because I get the impression that he wants the Mac. I just happen to agree that buying the iMac is the best course of action, based on my experiences with them.
But hey, if your Pentium 4 had torn up, good luck getting Dell/HP/IBM to fix it 5 times! "Please reset and unplug ze machine, sir."
