I cut and sort some of the negs I recently shot... That didn't take too much time...
Sitting down at the computer for 30 mins and fooling around and getting some results is the same in my book as my neg sorting.
But when I print... I PRINT! I tend to print a lot of negatives and dedicate myself to the task at hand. Had I moved to digital, I could see sitting at my computer for a day doing production work in a similar fashion.
Sure there is less setup and cleanup with digital, but there are similar small tasks that happen everyday on the wet side of the photography world too.
Just my $.02
