I'll agree that the Model S (beta) dash is an improvement over the Model S (alpha) dash.
My primary worry is that the gigantic center screen will be either washed out when hit by direct sunlight, or way too bright on a moonless night. I will concede that Tesla engineers are fairly clever folks, and I expect that this has already been considered and minimized. That the entire unit is canted slightly toward the driver shows that they are working on such problems.
I'll also muse out loud about the center screen whether it would've been better had it been mounted in landscape mode instead of portrait mode, to accentuate the open spaciousness of the cabin. Maybe the rightmost side of the panel would be too difficult for the driver to reach. Maybe such an arrangement would lure a 3rd person to sit up front, which is currently forbidden for some reason.
As for the banana leaf veneer, I "kind of" like it now, but I think it will grow on me. I know that there have been marketing study after marketing study about wood trim in the cabin, and the results have always been that it is associated with luxury and opulence. Walnut, mahogany, and brazilwood just -oozes- class and comfort. Ask any Gulfstream owner. And I think that the odds might have been fairly high that a plastic dashboard, no matter how it would be colored, textured, or polished, would be considered cheap and classless. And a "wood-alike" plastic trim is only used on the most mediocre of automobiles. The cheesy vinyl stick-on woodgrain exterior on station wagons might be passable for the first six months, but it looks horrible as it ages. Brushed aluminum or stainless steel looks pretty cool nowadays, but it conjures up the sense of stark harshness.
What would I have done differently? I dunno. Maybe have more places (or tuckaway compartments) to hold the usual automotive bric-a-brac that drivers and passengers have - sunglasses, phone charger cable, garage door opener, FasTrack transponder, etc.
