Another point about longer focal lengths. If you go from 50mm to 100mm, and want to maintain f1.8, you need to double the diameter of the lens (at least front).

I think is true for longer focal lengths, but it doesn't seem to be true in the 50mm range. The 50mm f/1.8 II has a filter diameter of 52mm. The 100mm f/2 USM has a filter diameter of 58mm.
