May be US is a bit slow, here in Hong Kong you can process digital
print anywhere in almost the same price as film print. Ten years? it
is a joke! BTW, a good quality 2MP DC is now in the $200-250 range,
normal consumer will not see the different in 4x6 print. They may not
need a computer too, the lab can burn their file into a CD for storage
and their memory card are free to use again. I think it is dirty cheap
as the lab are charging less than $1.5 for scanning and making CD when
you send your film in for D&P.

To my understanding, large format lenses has much lower resolution, I
don't think they can close to 50lm/pp. For DC vs 35mm, I always think
a 16MP (single layer CCD) DC will outperform 35mm film system in all
aspect including resolution. The time for an affordable 16MP SLR DC
system is coming soon, I expected it will be less than 3 years.
