I'm pretty sure ripster (at least I think that's who it was) has mentioned just getting a regular 7-inch screen and sticking it in that same spot. Then, you can have the same kind of functionality. If you like that, I think that's a better solution than relying on something that has it built in, since then it doesn't matter what the board is or if you switch.
I also think backlit is useless. But most of the boards I use are beige, so what the **** do I know.
