Old Velvia was 50ASA which was insanely slow, and hard to shoot with. Wonderful with tripod but handheld was hard. I actually found it a bit over saturated, though that's a matter of opinion.
Kodachrome's death wasn't so much caused by the continuing move to digital caused by the lowering of prices on Digital SLRs....that was certainly a factor, and continues to be so. Kodachrome was a unique film with a unique developing process and there was only one lab in the world still doing it. It was always a pain in the butt to use because of the process anyway: even in Toronto my film had to be shipped to a specific lab to get developed, or mailed to Kodak directly. I hated doing that...film gets lost in transition more than any other way, and the wait was long sometimes.
Fujichrome film could be processed in a standard E-6 process, and that was readily available in even small communities not so long ago. I switched to Provia a long time ago, and never looked back.
I'm going to go buy some tonight, actually, and it's going to cost a lot less than the $1,300 for the Canon 50D, plus it doesn't have that stupid crop factor that turns my ultra wide 20mm lens into an unimpressive relatively "normal" 32mm lens.
I'm waiting for an affordable full frame digital SLR before I move. Some will argue that the 5D is it, but I would certainly NOT argue that $3,000 is affordable. In the meantime, I scan slides.
We really need to solve the damn dust problem as well, though most people tell me it's overblown. Batteries can also be an issue for those of us who like to photograph off the grid.
