I find the info on the DX format particularly interesting. If I am understanding the chart correctly, a DX camera is just barely capable of meeting the minimum resolution required for a standard-quality print, and even then, only within a narrow range of f stops.
I agree that digital is lousy, to oversimplify heavily, but I am happy with the b/w prints I get from my 10D at 6x9 or 8x12 inches. They blend nicely with my film prints IMO. So resolution is obviously a very unimportant factor in the way I personally judge prints, I guess.
