[no substitute]

If I recall correctly, the six (at the time) cars that circled the 'Ring faster than a Cayenne Turbo, were largely Porsches. The Cayenne Turbo was approximately the same as a Boxster S.
Porsches diversification into areas that some don't care for, may very well be simple pragmatism. They have to have an answer for the cheaper and quick Asian made cars. The quality of the Porsche makes this choice a no brainer to me, and allows us to buy great used cars that will last. With two mid engined entries, albeit one well outside the boundaries of most of our wallets, maybe Porsche is once again considering steering away from the rear engined car. Say it isn't true? Well, we've had water since the 80's via the 959 heads, and most here wouldn't complain about owning one of those. Now we have full water, not to mention a V-10. Look at the early photos of the Boxster Coupe and consider how some here thought it looked as good as or better than the 996. The wave of the future?
Speaking of the future a recent TV show says cars with removeable wings are nearly here now, and will be the very near future of the personal vehicle. No, not that kind of wing. These fit on the sides of the vehicle and provide lift (flight), not down force. Porsche did tinker with aircraft engines for a while.
The times they are a changin', but the old air cooled flat sixes are still a lot of fun.
