Oh, I thought you had an Apple until I read the very first part of that.
I did have an Apple once (and an Atari before that, and one of them tape-based computers before that, I forgot the model). Then I got a PC and haven't looked back.
But never mind that.Your source is an Apple commercial! Oh good! Well they couldn't possibly be exaggerating or flat out lying. I guess that settles it then.
Funny thing is, in the last 7 or 8 years, I can only remember having had one bluescreen on one of 3 PCs, and that was due to a harddrive that crashed which is fairly impressive given that it was about 7 years old at the time and not treated with any particular amount of loving care. Only once have I had a problem that I couldn't fix (or rather, I gave up since it was more trouble than it was worth), and I'm fairly certain that was a virus. If your computer is causing you problems frequently, I can only conclude that the problem is somewhat more external than hardware and software.
Fact of the matter is, I don't trust a system that I haven't built myself. I don't know what kind of crap is in it, I usually don't like the specs on the crap that I do get to see (or the relative crappiness of the components is unevenly distributed and gives me a bottleneck somewhere so that I can't make use of the relative quality of the other components), and it's generally more expensive. I've never even seen an option to build my own Mac, and that alone is a reason why I'd never again get one.
