Additionally:
DPI of my 2011 laptop: 115dpi.
DPI of my 2011 monitor: 100dpi.
DPI of my 1997 monitor: 90dpi (100dpi possible at a rather ugly 60Hz)
DPI of my 1993 monitor: 91dpi
With this progress (or lack of) in mind, I think the pixel will be around for a while yet. Indeed, (thanks to LCDs) outside a few small-scale high-DPI places, pixels are more obviously visible than ever before! So why people are so sure that the pixel grid can just be ignored, I'll never know...
IBM once produced 204dpi desktop screens (T220/T221, 3840×2400 in 22.2")
AMD's high-end GPUs can handle 6 monitors each running at 2560x1600, and can render 3d content at that resolution with useful performance.
People are so keen to do away with the very idea of the pixel grid, and just pretend it doesn't exist, but the technology to display the result is just not there yet! Are we going to have to put up with even more years of blurry fonts and coloured fringes, just so that people can pretend the future is here, when it blatantly is not?
The problem isn't (and has not been in quite a long time) the content of the computer box, it's OS support for high-DPI screens and the price of screen hardware (IBM used to sell 204 dpi computer screens, 22.2" with a 3840×2400 resolution, you had to feed it with 4 DVI channels but it worked — for 2D anyway, the first generation shipped with a quad-gpu Matrox G200 MMS)
