Seriously, Microsoft Windows, you're being more and more of a **** by the day. Back off and respect the fact that people might just have an opinion that differs from yours.
EDIT:
To be on topic, The OP would be well served by a Topre, but I wouldn't worry too much about it. If they have a problem with your Blues, they should man up and tell you about it.
To be on topic with where this thread has gone, I don't think any OS is really THE OS (It's official, I'm making a linux distro called that now). I use both Ubuntu Linux and Windows 7 on my two computers, and it's a matter of different horses for different courses. For example, my Windows desktop is a media powerhouse, something I'd never do on a Mac (no BluRay), and that my Ubuntu machine is just not suited for (No software comparable to Windows Media Center that I like). Also, for the odd game on the side, it ha to be Windows 7.
On the other hand, I do some programming, and the Ubuntu machine fits the bill perfectly. Ubuntu pretty much set itself up out of the box (compared to someother distros) because I don't want to screw around with it. Some of the free tools out there for Ubuntu make life very easy, and I don't think I'd go to any other machine for programming.
tl:dr?
It's personal choice. Different OSs suit different users. Get over it.
