Likewise, typing on 2014 Mac Air currently, but my family's first computer was a Commodore VIC20 (I learned BASIC on that) and some years later my dad got me my own computer, an XT (8086) with a 20MB HD (how will I use all that space?!).

I loved both of those computers more than any I've had since.

Now I have a daughter. She won't be getting a Mac. She'll be getting an old box with some flavor of Linux installed and she's going to learn how to really use a computer (only if she's willing and interested, of course). The apps and windows will be there, but I am primarily going to focus teaching her command line and code. Otherwise it's just a gadget and a lot harder to love.
