These analogies don't work that well.
Back in the 20th Century, I thought of a computer as a collection of parts, and then, I bought my first complete machine. It was a little Win 95 desktop. It was cheap, and after the software failure recover wizard failed, it worked perfectly. It was all complete and came with useful utilities. I suddenly understood that complete systems were cheap and easy to use.
Of course, the reason that machine was so affordable was because it was little, and last year's model. I could scrape together enough money to replace it, until the year 2000. I missed out on Windows 98/NT, and bought a really powerful Win ME machine really cheap. Despite everything evil I heard about Win ME, that machine rocked! It came packed with useful applications and had a 40 Gig HD. ISFC worked perfectly with a dial-up modem on that machine. Then, I put a video card in it that destroyed power supplies. Oops.
Getting tired of replacing PS's, I bought my first XP Pro machine. It was a PoS. Oh, it worked pretty much like the ME machine. It was just slower. It also got every virus on the internet, despite anti-viral software, and then I made the mistake of buying Norton's 360. Back, in the days of DOS, Doc Norton was your friend, not any more. I tried to go "Cadillac" when I bought my Vista machine, but that was a mistake. Vista was not released as a usable OS. I quickly tired of going through the registry to pick out keys for software that failed to install correctly. I fell back on XP. I never liked XP. I just haven't been able to use Vista and Win8. My only experience with Win 7 is with my employer's machine. I still don't understand what people liked about Win7. I do not appreciate the way it handles overlapping windows. I still prefer XP when I'm juggling a half dozen spread-sheets. A little continuity would be nice.
