To be fair to the ad, I think they mean it in a funny way when they say "PC users may have to justify themselves" but even then, it comes off as the usual crap of "if you are a PC/windows user, you are not hipsters like us who are on mac".So the intention might be good but I agree that it probably is not the right place for it. I personally use a dell laptop for dev work at home where I have partitioned windows 7 and Ubuntu and switch to either as necessary.
