There is a thing. The 24" LG we have here is actually a "dumb" set - no attempt at all at trying to be an all-in-one streaming device, it's literally just a television. A little hunting in your size range will probably turn up at least a few options in the dumb range, rather than being "smart" out of the gate. The "interface" will be familiar, the only real issue will be how well the remote actually operates in practice.
