Miniscule pixels would make nicer looking fonts, but I don't think it would fit in very well with the current way we render images to be displayed. Current E-Ink pixels are roughly 100 microns in size (for a 250 dpi display). 1 micron pixels would increase the size of the display buffer by 10000 times. So, from about 1 MB to 10 GB needed to be computed and transferred on each screen refresh. That would make updating the screen intolerably slow using today's technology (especially in low-powered ereaders). We'd need something different for such displays, perhaps some kind of vector rather than pixel renderer.
