I think the "advantage" of a threadless headset is in the adjustment. Throw in a face plate stem and you can easily swap stems and bars. But really, how many people do that? So again, it comes back to adjustment. Threadless is so simple and requires what a 5mm hex wrench?!
As for your question as to whether carbon wheels are "dumb?" Depends on what you want. One reason why tubular tires are so popular again is that with a carbon rim wheelset, you can get a total wheelset under 1200g and 1000g is not unreasonable! In contrast, a standard wheelset is around 1700g or so and carbon clincher wheelsets are around 1400-1500g. So for the weight weenies, a tubular carbon wheelset can save as much as a pound.
