I agree that the 1920*1080 resolution is adequate for watching movies, but there still are a lot of people like me, who spend much more time reading texts than watching movies.
An acceptable display for reading texts must have a height of at least 12 inch (30 cm) to be able to read A4 or letter sized pages at their actual size. The best existing displays of this size have a resolution of only 100 ppi (Apple Retina displays do not matter because they are too small). At such a resolution the shapes of the letters are severely distorted and one must use only special typefaces designed for low resolutions (e.g. Georgia) to be able to read comfortably for many hours. If the resolution would be increased to 300 ppi, that would be a great progress and it would allow an acceptable rendering of many more typefaces, but the quality of the display would remain much less than the quality that was already achieved by the books that were printed two hundred years ago.
An even greater resolution is required to finally match the quality of the printed paper.
I am very happy to learn that Intel will finally push for better display resolutions, but we must not forget that this comes after 12 years (2000-2012) during which the resolution of the displays remained absolutely constant. It is true that during these years the large & heavy CRT's were replaced by much more convenient LCD's, but that did not result in any resolution improvement.
In fact during the last 5 years, the *average* resolution of a notebook display has diminished considerably. In 2006 I could buy cheap notebooks with a vertical resolution of 1050 lines and medium-priced notebooks with a vertical resolution of 1200 lines.
Now all the notebooks are provided with cheap TV screens so the typical vertical resolution for cheap notebooks is 768 lines or at most 900 lines and only the most expensive models are available with a vertical resolution of 1080 lines, which is barely adequate for reading.
In conclusion while these actions of Intel are commendable, it is not like that they have discovered anything revolutionary, it is just an acknowledgement that the lack of any progress during the last 12 years towards the goal of being able to read a book on a computer display as well as when it is printed, can no longer be accepted by many users.
