Thats a long list of requirements and yet none of them apply to me as well as the other people I work with.

As a software developer I always use the same computer and I have never needed to type on someone else's computer

So you don't share your computer with kids or the spouse (you have money or no spouse/kids), don't teach, don't do much on site user support, don't visit much clients, don't travel for pleasure or family much, don't use much virtual keyboards, are not at a university, etc.

It's not a good or a bad thing, but it would be a mistake to generalize it.

No, I don't do those things. Sharing a computer is a fairly uncommon activity for me and most people I know. And even if it is something you need to do every now and then it is always possible to add an extra layer to your kb config which is the standard layout so other people can use it.
