I often have the reverse problem. I am happy enough with a schematic and
soldering iron, but trying to dowhat many here would consider to be
trivial software-related tasks can be a major effort for me. But I

Becasue of my hardware interests, i find beauty in a well-designed bit of
electronics, for example/
That aaid, I do like particularly unusual bits of mechanical design too.

then? The 'Insert', 'Delete', 'Home', etc keys. The Windows-specific keys
(which the keyboard driver here does nothing with, but they're still on
this cheap keyboard)?
If you mean very special and specific keys, I guess they rather limit the
sort of software you can run, or at least which will make sensible use of
