It's worth bearing in mind that the 600dpi/1200dpi of laserprinters really is dpi - dots of black (toner) and white (paper), while the 180dpi of eInk is really 180ppi - pixels of black, dark grey, light grey or white, which is 'equivalent' to about 300dpi.
Of course, the 'equivalence' numbers are only a guide, and are more applicable to continuous tone images (e.g. photographs) than text.
For example, I'd much rather have 360ppi eInk at 4 grey levels (600dpi 'equivalent') than 180ppi at 16 grey levels (700dpi 'equivalent'), even thoug the latter has a higher dpi equivalent.

I'm one of those folks who is bothered by the difference between a good 600DPI laser printer and a good 1200DPI laser printer (emphasis on "good," as there may be no difference between units that aren't good). The ~180DPI res we have on current generation eInk readers is just barely sort-of kind-of acceptable.
