There are actually a few different 4Ks. When pro-quality digital film cameras and theater projectors say 4K they mean 4096 × 2160. 4K UltraHD is 3840 × 2160.
However none of those definitions are close to 4096 × 4096.
That was the first thing I though of when I read it. Microsoft's unreleased next gen browser is faster than current generations of it's competition's browsers.
That would be the minimum bar of acceptable speed improvement in my mind. If it was faster than the others in-development versions I would be impressed.
This is not news at all. This is the same thing they did with the Vista launch. This plan was rumored months ago.
During a period before the next OS release anyone who buys a computer with the old OS will be able to upgrade to the new OS for free, via their OEM.
The are NOT giving all the Vista users a free upgrade.
