Or do most people lack the cognitive ability to use more than one OS, and need crappy 'Microsoft Essentials' classes to teach them anything beyond how to game and access their Facebook accounts?
They lack the interest the same way someone who learns driving an automatic usually has little interest in learning to drive a stick-shift (actually, here in Spain there are very few automatic transmission cars so everyone needs to know about the stick-shift, but I digress).
I deal with last-year undergraduates who still don't know about Word styles, who still write the content tables by hand (because they don't know about the possibility of using the title styles in their Word documents). Believe me, they don't care to investigate in most cases.
Actually, most of them still will put text walls in their Powerpoint presentations so they can read them. And yes, they usually had classes about it in high school. But they didn't care.
Mind you, I'm not even talking about changing to Linux or some open source program. I'm talking about students (teachers too) persistently asking for Windows XP-compatible software to be installed in their Windows 8 computers when we aren't allowed to do it and asking for us to help them when the magically appearing copy of our licenced software doesn't work with their computers' Windows 7 or 8</semi-rant>
So no, they usually don't know better: they stumbled upon the software (or were taught to use it by someone who already used it) and never looked back. I have even had teachers tell me (because some licenced-software seller told them) that the costless option I suggest is worse when the licenced version is the same software with some useless extras bolted in (and yes, I mean useless extras because they can be substituted with standard Windows software).
Palestinians who were responsible for the killing of Israeli children after the establishment of the PA in 1993 also benefited from impunity.
Update: I found the reference you pointed out. Great work putting a link that explains next to nothing about your point of contention. Next time, link the document itself.
Trying to code on a hunt and peck thumb board that required escapes for most punctuation symbols was a waste of time.
Because you couldn't change the mapping, right? I agree that it's not the most comfortable keyboard ever, but I'm typing quite quickly with it, thank you.
And I'm a leaker.
That's what sanitary pads are for, you know.
