Yup. TFT LCDs are in everything because they are so cheap, and they make designers who are used to designing for computers feel less constrained.

I have indoor and outdoor air quality sensors in my apartment; the outdoor air quality monitor is an LCD and the indoor one is e-ink. I kind of like the LCD better, but have to use a feature to turn off the screen at night so it's not illuminating the entire room with its backlight. The e-ink doesn't emit light, but it also doesn't update as frequently, so it's often displaying information that's out of date. Because of the various pros and cons, neither technology seems like a "win" over the other; the product designer has to pick one and hope the market agrees. LCDs get the nudge because of cost, though.
