Personally, I think all this crazy high resolution stuff -- Apple's retina in laptops, 4K tv's under 100" in size, etc. -- is ridiculous. In some cases, such as too high pixel density on a computer monitor, it is even detrimental. However, being that 4K is likely to become all the rage and with Apple's pushing of Retina, how long do you think it will be, if you think they will, until they release a Retina TV, touting either 4K or some other incredibly high and dense resolution.
I wager two years. What do you think?
