Think about it this way: If you loose 5 days of productivity then you have lost $500. A Windows or Linux machine is guaranteed to cause many more days than that of productivity loss per year.
And with "normal people" I mean everybody who is not a developer or hacker, including millions and millions of people who work professionally with computers.
The RAM doesn't matter as much as people here insist. What do I care that my computer has half the RAM, when it completes any and every task blazingly fast and never freezes up or crashes? RAM turns into an abstract.
Look at it this way: You're arguing that a diesel truck is always better than a motorcycle because it has more horsepowers. Okay, but the motorcycle gets me where I want twice as fast and is more comfortable, and doesn't break down all the time. That's what I care about.
