Transflective LCDs are used nowadays (as opposed to just reflective), my Pebble has one and the Daylight Computer is another modern device with one.
They're great if monochrome IMO, but the color variants suffer with brightness as each subpixel can only reflect 1/3 of the light, which makes the backlight necessary in more situations.
