"significantly better in the sunlight" is not how I'd describe any pre-backlight Gameboys, honestly (including the original). The levels of light in which you could usefully play them were a very narrow band that I would describe as "lots of ambient light but no direct light at all". Hell even most of the front lights you could mount on a Gameboy created unviewable hotspots of light around the edges. eInk has a much much wider range of workable light levels than any lcd I've used, with or without a backlight. The recent trend away from diffusion layers on lcd glass has also made it a lot worse.
