The E-Ink Spectra 6 displays [1] released last year has full color gamut, thus beating any other display technology in an outdoors scenario. The problem is that they take something like 12 seconds to refresh and I haven't seen any consumer devices using them.
In the near future I think spectra displays will be excellent for readers when they manage to get the refresh a bit more speedy, while ironically the B&W displays with color filters will be the E-Ink technology suited for tablets and phones in general.
