Clearly there's no difference in effort between a day installing and configuring a Dell server and several thousand person years of writing a solid, scalable operating system, so your question is perfectly reasonable.
I understand that what I'm saying is a bit of a stretch, but when they claim people don't love computers for not doing that they're doing, they may as well take it to the extreme. People have written operating systems, maybe these people should say everybody else doesn't love computers.
I mean, obviously I don't expect anyone to build everything they use. My argument was aimed at the "you don't love computers" statement and not at the fact that they don't write their own OS.
