They're also much more expensive, have fewer input options than my current (dumb) tv, and have some remote configuration options that would more conveniently be put into menus, in a consumer device. So...what's the point, besides pigheadedness over not buying a "smart" TV? It's not like there's a way to even go see what I'm buying before I do it.
I'm not a big fan of smart devices, but I'm not going to pay more for a display with "meh" connectivity that doesn't really seem to be optimized as a home entertainment device. Although annoying, it makes more sense to buy the smart TV and ignore the extra features.
