Yeah, it's totally fine, as long as you have both side mirrors. It'd be nice if they put bigger mirrors on the side if they're killing the rear window though. Although they're pushing a screen to replace the mirror, I guess.

I haven't used one of those in a while, but I did have a rental with a screen / mirror and found it really strained my eyes to change from far focus on driving to near focus on the screen... Might be better when the screen is not also a mirror, I could kind of see the mirrored image if I was far focused even if the screen was on... it was pretty distracting until I figured out how to turn off the screen part.
