I do a lot of very "serious" things on my computer.  That's why I haven't bothered with Vista.

If the whole Apple commercial thing isn't Macs vs. PC, then there are a number of commercials in the series that make no sense at all.  And, why call the other character "PC"?

I disagree with you on the "smokescreen" argument.  You are welcome to the opinion, but I don't see it as based on fact.  Either the OS is immune from attack or it's not.  Either it's an attractive target to those who want to do a lot of damage, or it's not.  If the reason isn't market share, then I'd love to hear what is.

Could be worse, could be raining.
