To me, it's not. I want the real thing, all in one piece, without a single missing feature.
The only time "webOS DNA" is good enough for me is when this DNA is the operating system, like LG is doing.
I don't watch TV, i don't like paying for cable TV, so i don't. I haven't watched a recently-released movie since Coraline (a stop-motion animated film about a girl who discovers a parallel universe where everyone is a "better" copy of the real world but with buttons stitched over their eyes)
I only watch YouTube, on my Pre+ or the Touchpad. But if the LG webOS TV comes out, i'm interested.
The other guys appropriating features, is only "other guys appropriating features". They don't have the soul, they don't have the dedication that the engineers at Palm had or the Homebrew developers here have. I'm not saying "oh band x sold out i'm not listening to them anymore", no, i absolutely mean that even though our project is running on vapors, the other guys get spoiled by having easy exposure and start producing turds like Apple Maps.
