Any time I've ever seen a tablet at the table, it's been used to push annoying ads at me trying to upsell shit. No, I don't want to add a wicked bloomin' onion or a Chocolato(tm) margarita. I don't need a flashing squawk box bothering me while I'm trying to have dinner, thanks. While I'm sure you could design a table tablet that didn't do that, it's obviously too tempting for them to do it.
