Most people still work at small to medium size businesses, and depending on business type and density, it doesn't make sense to have a machine like that. Those big machines aren't inherently better, they've just faster at serving lots of people, but at the expense of cost to run and service, and that cost can be a lot (especially the up-front cost to buy).
As for downvoting, I guess people thought you were being dismissive of smaller workplaces? I dunno, I'm just guessing there, since I didn't feel the need to downvote you.
maybe it's different where I'm at. I do work at a lot of big places, but right now the company I'm at is small to medium sized (they recently bought another company in another city so while it is probably a medium sized company now it still feels small) and it has a machine.
Also at the big companies I've worked at often you have a small room with a self contained team and each of these teams has one of these machines.
