Front lighting isn't always ideal because it increases the distance between the screen and the user and makes it feel less paperlike, which is why Remarkable isn't front lit. It also uses power. Both types of displays don't need power for light, which is a huge advantage. The power advantage e-ink has is not needing power to retain an image. While that's a requirement for some use cases, they should both have very low power consumption compared to backlit lcd screens.
