Porsche created and developed PDK 30 years ago for racing. They used it in the 917 I think at Le Mans. So it's not a new idea by any means. It has taken some time though to engineer it for the road where refinement, reliability, longevity, and noise are far more critical to the buyer. Just as important if you're Porsche you need to keep the weight down and that takes time to balance out with the objectives listed above.

I'm sure it will be nice, but I still prefer to tie my own shoe laces rather than have velcro fasteners...
