All hydraulic clutches are like that. You notice it more as the clutch pad wears.
It's strange because the owner's manual says not to let the Boxster sit at idle, rather drive it immediately. If you do that, the clutch is stiff. If you let it warm up, cat fire risk. That, and it's all backward from what your dad said to do when you were a kid. I'd been warming my cars up for 10 minutes like dad said for years until we got the Boxster and I read the manual. Then I read the manuals to all of the other cars and I was doing everything wrong!
