Isn't nice that ISO measurements are more intuitive? 400 is twice as sensitive to light as 200?
I actually like the old DIN system, but I'm weird. ISO works great, and it (and ASA, sort of) did win out over DIN.

With our digital wands, we can more f/stops in tighter increments.
Actually, with my old, analog, aperture-ring controlled lenses I can set the aperture to anything I want in between the markings, but my cameras only offer full stop shutter speeds. Gain some, lose some. =)
