How much would you pay for the computer Linus used?
That's an interesting thought.
But let's keep this on authors. A typewriter is a mechanical tool, the good ones were expensive and of good quality, and once you had one, there was no real reason to "upgrade." OTOH, authors today may go through a computer every 2-5 years on average, and may have more than one at a time. I don't see an author in the nearterm future only having one computer their entire career, unless it's a really short career.
