Earlier quoted context omitted.
I never wanted one because I was afraid that one or the other would break, then it would be half-useless. My parents had one where the TV part stopped working, but the VCR still worked. It had video/audio out jacks so dad plugged it into their other TV, so they had a dead TV sitting next to their working TV for use as a VCR.
Smart TVs from at least the last 5 years have a similar problem. You update the software and they become excruciatingly slow, or you can't update the software and they gradually become useless. Damned if you do, damned if you don't. But I can replace an old Roku for $39.
Though the good thing is that I can't see the carcass of the old SmartTV laying around, the TV stays connected to the Roku so unless I accidentally hit the Channel up/down button and switch it to TV mode, I never see the LG SmartTV features.
