While I don't think the keyboard was the only thing that ruined penmanship (also the lack of snail mail, in my case, growing up around medical handwriting, etc), I do think basic math skills don't qualify as "no relevance".
I was behind someone who bought something, and they mistyped in the amount of money he gave them. The kid cashier, asked for a manager to get him more money for his drawer, because the change said $500+ back. So the kid has no basic math skills, and worse yet, no common sense. (get more back then cost) I frequently have seen kids that can't read an analog clock (things that won't be disappearing from places like Big Ben anytime soon). And I still wonder how kids "sign" their name, because when I was growing up, sign your name, meant cursive, on legal documents.
I also think stick driving still has relevance, as so many delivery vehicles still use it (UPS, Fed Ex, pretty sure the post office LUV's). But it is not any different then hand tool skills. Not everyone will use it, so relevance is a variable.
