David Shapton at RedShark has a great article commenting on the Paradox of 4k right now.
It kind of feels like the initial switch to HD, but more so to me. And I think his conclusions are right. For stuff that will have a shelf life, moving to 4K makes sense as it is much more future proof (2.4 Megapixels to 8 Megapixels) but for current one time view events like news or sports it really isn’t too important. Especially since not only are most people OK with HD, but there really isn’t any 4K content as of yet, and won’t be until bandwidth issues are fixed (1 GB fiber to whole cities would solve that).
And you have to wonder how HD material looks on a 4K set. If it doesn’t look as good as an inexpensive HD set, then why move to 4K except for bragging rights?
