My former '99 Boxster was a TipS and I thought in many ways it was the best of both worlds.
Around town, it was much easier to keep it in auto mode and when I wanted, I could manually shift it.
If there were anything I would change, or maybe I should say add, it would be the option of either shifting with the shifter and the steering wheel, sort of like the old 'Sportronics' that Porsche used in the '70's and '80's cars.
The TipS is much cheaper to maintain over time and these cars seem to suffer fewer (or at least fewer incidents) of the 'normal' weak spots in the car.
My new-to-me 911 is a 5-spd., but I don't think I'd have been unhappy were it a TipS. Lots of the 911 guys love them.
Love my Tip, and on the rookie end of DE's I am faster because I can concentrate on line and driving without having to worry about shifting. I actually only on occasion use the manual mode ecause it works better than I can drive. Ed
