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.
