mrtd: ""Does it look pretty?", and "How easy is software development?" are a lot further down the list for most users. I suggest that things like "what sort of multitasking does it have", and "does it have proper drag and drop" are even lower down the list."
As you admit later on, those factors have an indirect effect on the decision-making process. Moreover, as developers, these are factors that Acorn's successors have exclusive control over - they can't as easily influence the market at large or which friends you choose to keep.
mrtd: "1. A love of innovation and elegant technology
2. Dislike of Microsoft/big business/monoplies
3. Grew up with Acorn, like RISC OS, (possibly tried Windows and didn't like it).
4. A desire to be different."
(1) Whilst some new developments are making RISC OS machines more attractive, I'd hardly consider the RISC OS scene a hotbed of innovation. (2) I dislike Microsoft, too, but somewhere along the line you'll have to buy something produced by some big company. (3) RISC OS was nice in its time, but it's good to see what else is out there. (4) Computing platform is one of many lifestyle choices available to the modern individual.
