Oh, ye of little faith . . .
I drove a manual Celica for six years. I loved that car.
BUT there is a big difference between a manual Toyota and a manual Porsche. You guys might not realize it, but the Porsche clutch is a monster. :troll:
It is really hard to depress, if you don't have muscular legs. It can be very fatiguing for a woman. I've had this conversation with a friend of mine (who bought herself a new 911), and she opted for the PDK. She test drove a manual, and after about an hour, her knee ached. I've driven hubby's manual 911, and it's just a bit difficult after a while. Which drains the enjoyment right out of it.
I've also had the PDK versus manual conversation with hubby, and he wouldn't give up a manual if you paid him.
I think it's just a personal preference thing.
I said it once, and I'll say it again; when hubby and I race, he's over there shifting like mad,
while I'm putting on lipstick. 
He only beats me by less than half a car, even with all the extra HP. Oh, and mine doesn't "lag".
