If they have something I need...
...and I can't find it on the internet cheaper, then yes, I'll go there.
Last I heard, MS isn't thumping baby seals at their company picnics or paying 7 year-olds 13 cents a week to build their products, so I have no reason not to buy it.
I don't dislike either Windows or Apple. They're simply companies that build products. I have products from both companies, and they do exactly what I want them to. I don't sit and complain about how horrible Chevrolet is because my truck won't make me breakfast, because my truck wasn't built to make me breakfast. I don't complain that my iMac won't run Windows software, or that my Win7 machine won't run Mac software, because they weren't built to do those things either.
I haven't seen a BSOD in any of my machines in 4 or 5 years. I don't surf porn or download free wallpapers, and I don't ask my machines to do anything else they're not designed to do. They work perfectly.
I'm guessing if I tried to modify my truck to fly me to the moon, it would crash too...
...and guess what...I'd have no one to blame but myself.
