Yeah, not everyone is like I am. I know every last detail about my system because I built it and I love it. I'm the same way with my drumset. That's just how I am though. I've met some absolutely amazing local drummers who are far better than many famous drummers (hey, it's not easy to make it big even if you're good), and when I ask them what their drumset consists of concerning the drums, heads and cymbals, some of them don't even know! It's not due to renting their equipment (many professionals have to rent on occasion), but it's just that they have a personality type where those details aren't important enough to remember. All they care about is making music.
So, I feel that some people are the same with their computers: it's more important to them to use their computer than to know what the system consists of. So when they want to know what it consists of (or if someone else wants to know), they're naturally going to seek an easy way to get that information. Fortunately, we have some software applications that do a very good job of getting almost all of that information very accurately. As I discovered today, HWiNFO is one of them.
Or how about some people with the car that they own? Have you ever met someone who doesn't know very much about their car, almost like it's a rental or something? I mean, I think that this is just one of those things and that's fine.
