The problem with ¨All - in - one PCs is that the replacement of
replaceable units is much more expensive than in a desktop PC with separate
monitor, since you are stuck with the same manufacturer (manufacturer
lock-in)
Example : Currently the graphics card in my desktop PC randomly stops
working and I have to re-start the PC.
Following arrival of a new graphics card (more up to date model at similar
price as exiting one) it will be simple to change the card.
A desktop PC + separate monitor might involve more space and cables but is
so more versatile.
