Over here, if I use "normal" slide film, which is not necessarily 
any worse than "pro" films, I'm at about $3 per 36 exp roll. That
would shift the break-even point a bit. Plus, the quality is just 
not comparable (yet). And what are the extra costs per additional
microdrive? You will definitely need some at your shooting rate.

This is true. But I don't scan every frame I take. In fact, I scan
a rather small percentage of my *keepers* only. Also, dust spotting
a low res scan is obviously not as labor intensive as a high res one.
And until now, my scanning is for Web use only. Dust spotting a 600x400
image is still work, but it doesn't take an hour with the right tools.
OTOH, if I'd try to project a 2-3 MP image to a size of 2x3 meters, the
quality difference will show. Plus, I'd need an appropriate projector
first. Not exactly a cheap accessory given the output quality. I don't
know if there are projectors for "high res" images (more than the PC
typical 1280x1024 size) If there are, I expect them to be pretty darn 
expensive, given that the prices for projectors for PCs are already very
expensive and only support a *very* limited resolution.

As you said, the mileage varies. It always depends on what you do
and where.
