I thought it was the other way around, with multiple 'beads' per pixel, but it looks like it's rather one bead/pixel.

That eink link claims that 'Electronic ink is made up of millions of tiny microcapsules, about the diameter of a human hair.' Now, the diameter of human hair varies a lot, but 75μm seems like a reasonable estimate. The Paperwhite is supposed to have a 212ppi display, which would mean 120μm/pixel - larger, but the same order of magnitude as a hair's breadth.
