They're still used in fitness watches: IIRC most of Garmin's current line has transflective displays. They fill a somewhat unusual niche: if you're willing to sacrifice display resolution, most of your color space, and pay more money, you can gain incredible visibility in direct sunlight and great battery life (by not having to use the backlight as much). It makes perfect sense for a watch or a Gameboy, but it's a tough sell for a laptop or tablet where most of the use is indoors. That said, the moment someone tries to crowdfund a laptop with a reflective display, I'll be the first backer.
