Splint's got it right. From what I've heard FROM WOMEN, women spray more urine on the toilet seats than men do. And ironically, they say the reason is that women don't want to sit on public toilets, so they "squat" (stand) instead. I think America should replace all its toilets with those in-the-floor toilets they use in some countries.
"If you own a computer, the choice is a no-brainer." Not at all. Watching movies or TV shows or playing video games on a 15" monitor can never compare to watching/playing on a 50" HDTV. All of my friends are tech-savvy young people with multiple computers, but they all have at least one large HDTV.
