I don't get this whole "Xbox vs PlayStation" war.

Now, I know this has been going on since forever and that this thread will probably start a Xbox VS PS argument (because you guys are so damn predictable), but I truly don't understand this huge uproar over which console is better. I like to think I have a unbiased opinion on the matter; I owned both the first and second PlayStation. What made me switch to Xbox with the 360 was my boyfriend owned one and I liked some of the exclusive titles more. That's basically how I decide on which console I want to buy, and it's how I'll decide on which next gen console I will be purchasing as well. However some people will stick to a certain console just because of the manufacturer and the name, that to me is silly, especially when you feel the need to bash other consoles in the progress. Who the hell cares? I was just after watching a youtube video where people were talking about the new Xbox not being able to play used games. I can understand how that would turn people from buying the console and make people upset, but some people were actually HAPPY because they want the new Xbox to fail, they want people NOT to buy it. Once again; WHO THE HELL CARES? Why do you want a product to do miserably? How does that benefit you? Why do you care what other people buy? I just don't get it! If you want to stick to PlayStation because that's what you're familiar or vice versa, fine, I get that but WHY do you care if more people buy an Xbox or a different console?
