Why do you assume a Mac is there to be "better". Whatever a company makes, that is pretty subjective beyond what hardware it has.
A Mac offers an alternative. Some people like it, and everyone has their own reason to, be it simply the design, the interface, the way in which Mac OS programs work, how the system updates, the environment for the average end user.
I used a MacBook as my main computer from 2008 to about March of this year. I currently use a Compaq now as its one of my favorite PC brands. I don't see either as more superior, Mac OS just offers an alternative that I find nicer to work in personally for writing documents, organizing photos, organizing music, doing any webdesign work, and other general tasks. In saying that I've never really liked programming in OSX outside of web design, and gaming always feels odd even after Steam (to the point I'm not interested in Mac gaming at all anymore). I also prefer web browsing in Windows currently, but that might be just because this new computer has a bigger screen lul.
My point is, Mac and PCs offer different things for different people. There is no best computer for everyone. And just because you aren't interested, don't understand, or don't want to own a Macintosh doesn't really justify calling it a terrible useless product. And I think you'll find whatever you think, Macintosh computers are acknowledged worldwide as highly successful consumer products that have changed computing. No anti-Mac sentiment will change that ever.
