Some crude back-of-the-envelope calculations for resolution needed 
for digital cameras.

Assuming 100 lines/mm needed (about what reasonably good film 
resolves):

With 25.4 mm/inch, then a 35 mm frame is 25.4 X 100 by 1.5 X 25.4 X 
100. This is 9.68 million pixels.  With 30 bits per pixel (assume 4 
bytes) this is 38.7 MB per photo.  Note that many cam corders 
advertise 300K-400K pixel resolution. Without image compression wee 
would need a 1.4 GB hard drive to store a 36 exposure 'roll'.

Just a thought about how far we need to go before film will go away.
