I definitely like the decluttered "flat" look, and think it will improve performance (especially on the MCU), but dislike the removal of information, such as the temp on the IC. I don't want the analog clock at all, I hate them, especially w/o numbers! The little Model S icon should be selectable, It might be nice to see when the brake lights are on, but otherwise it's a lot of graphic noise.
I suspect this is why it's in EA/Beta. We'll probably get more refinements before general release. If everyone was getting this release, we'd have more reports by now. I can find only one.
