I've been an IBM compatible user for 27+ years. Lies or ignorance, which one is it? I'm serious. Aside from that, you're either intentionally leaving out the things that the MacBook has that your Dell doesn't, or you're completely ignorant to their existence. Two years ago, I had a MacBook Pro that I bought for $1,600 that I KNOW would rape your Dell. The best way to describe the way I feel about Windows is to compare it to a truck stop hooker, running from truck to truck, sucking off one dirty trucker after another. You can't lie to me about what Windows is and is not. Why is it that people like to assume that Mac users are ignorant of Windows? I know a lot of 'switchers' who spent years on WIndows before making their way to the Mac. Even if you think you haven't had a virus, you wouldn't know because, as you've stated, you don't run antivirus.
In any case, it doesn't matter how long you've used Windows, it doesn't change the fact that you're a liar. First of all, Windows has only been around for what, 24 years now? Even so, most people didn't use it until at least version 3.0, which was around 1993.
