I have difficult to see what advantage webOS has on a TV. With no touch (?) they need to completely redesign the interface anyway.
Sigh. I really find TVs with enhanced features that useful. The problem is that the software goes out of date very quickly, and I am entirely dependent on the TV manufacturer for updates, which will likely stop shortly after the TV goes out of production (which is what, 6 months these days).
All I really want out of a TV is good picture quality, and a bunch of input ports. For video streaming, gaming, and other apps, I prefer to have a separate box for that, which can be replaced and/or upgraded less expensively.
