I had an Apple laptop with a removable battery (an iBook G4). It even had a button and LEDs on the battery to show the level of charge, like tool batteries have nowadays. And not only was the RAM upgradable, it could be done toollessly because the keyboard could be popped off just by undoing a couple of latches.
That was standard for decades.
Most phones, too.

I remember if you dropped a phone the battery would sometimes go flying out of it.
