lt cap,

I agree quite completely. Two model years ago, I dropped 3k on a Samsung top of the line 55" 4k tv. It still melts my eyeballs, esp. given the fact the it upscales feeds of lower resolution, and serves as a terrific gaming monitor. But what you can buy now for a great deal less is pretty stunning.  Even if you dig into the specs and find some deficiencies, most eyeballs won't really know the difference. I agree we are pretty close to a cusp in the change of TV resolutions that most viewers will adopt. Netflix, Amazon, and other content providers are already making the transition of making 4k content available, and I can't see that trend doing much of anything but gaining momentum. One metric to watch is that 4k disc players seem to be around $350 - $400. (There are no 4k DVD-like discs that I'm aware of. What?) I recall that the first DVD players were about $400. They're so inexpensive now, they're almost disposable. The quicker we get there, the less our optical networking stocks will suffer :-)
