"only those with deep pockets can afford to buy both the display and the appropriate amount of bandwidth."
I disagree...
I saw a 39" 4K TV yesterday at Tigerdirect for $299

Netflix requires roughly 25Mbps for 4K streaming.
I'm lucky enough to get 56.8 Mbps and I'm currently on a deal for $64.99 per month WITH basic SD cable.
You always get what you pay for. Latest tech for only $300, there have to be some tradeoofs.
Yeah, that TV is limited to 30hz at 4k, which is absolute garbage for anything another than movie watching.
