Why was the AA LiIon size ever invented if it's no good?

Because its one of the most common battery sizes.

But due to it's differing voltage, it was never intended as a direct
replacement, but to power new devices that wanted more voltage, such
as
LED torches.

But some arent ideal with 18650. There are in fact one
hell of a range of LiIon cells of various sizes and if it
wasn't for the problem that LiIon doesn't work well
in the smaller diameter cells, it does make sense to
use an existing very common cell size.

But that problem is significant. And a single 18650 fits very well into
a
pocket torch or anything else I can think of except a mobile phone.

Not just mobile phones, tablets are too thick with those.

I'd forgotten about tablets, as I think they're a pointless invention.

More fool you.

Who wants to scrape their finger around on a piece of plastic all day?

Those who use them don't. And the screen is glass, not plastic, stupid.

Same with wireless mice and keyboards.

Those use so little power I just stick alkaline in them.

I do recharge mine. The keyboard has a fixed liIon inside, like a tablet.
The mouse has an AA that I recharge in a charger, with an alternate.
