>Text and windows for reading and development are fine, and I often use tiny fonts. I don't see the hype.

That's because you're looking at elements hinted for and designed for a blocky pixel grid. Try rendering a typeface designed for print, and the difference is night and day.

There is no hype. Until displays can go toe-to-toe with print, we have a long way to go. Hold a magazine or a book up next to a standard-resolution display (with the same body font!) to illustrate how inept standard-resolution displays are.
