Thanks for posting my images Norbert!
Elon actually drove onstage with eight people in the car. They had an extra guy hidden in the frunk! Also everyone in the car had a knapsack with him, including the guy in the frunk. Nice stunt.
Elon demonstrated using google voice to find music online in the car. The touchscreen is a full web browser. The GPS shows satellite imagery, and it looks amazing in full screen mode - and the route instructions appear on the spedo console display, so you don't have to look over to the big screen. The car controls are pretty cool; for example there's a slider for the pano roof and the roof follows how far you slide it.
Incidentally the touchscreen does not appear to be angled but is rotated slightly towards the driver, which is why it looks tilted in some photos.
And yes, sport version has 0-60 in 4.4s and will be available at launch. Elon actually forgot to mention it during his presentation, so they dragged him back on stage, at which point he joked about doing the "one more thing" bit.
