As a 1V owner:
1. You will never even remotely use those 45 points. If anything you'll probably set the thing to zone out on it's own and not mess with it.
2. You will never download data from it because a: who cares, b: you won't find the cable, c: you won't find the software.
3. The 1N is a perfectly usable EF autofocus body that will burn film all day and night with the best of them. At the price Bruce has it at, it's quite a decent deal.
Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
