We're still using our 32" Samsung flat-screen from around 2007. It's just a regular (non-smart) TV. It has RCA inputs, which are important to us so we can connect our DVD/VCR combo (We always watch
It's a Wonderful Life in black and white on Christmas Eve) and also play games on our Wii™. In addition, it has an HDMI input so we can connect our Firestick™. DW would like to move it to a different location but that space needs a larger (around 42"-44") screen. DW is probably even more frugal that I am so she told me she can't see replacing a TV that still works just fine. If our old Samsung ever dies, then we'll probably get a new Samsung. But we'll probably have to find some kind of adapter for it, as I don't think many TVs come with RCA inputs anymore.
From a longevity standpoint, we're happy with Samsung.
