With all due respect, but I disagree with the above statement completely. When I'm trying to shoot a warbler on the wing hunting for insects or shooting macros in even the slightest of breezes or shooting super-telephotos when I can't open beyond f/4, I need to crank up the ISO as high as I'm capable of doing so for the intended purpose. Right now, I'm stuck at ISO 800 with my current camera for images I intend to sell up to 13"x19". It used to be ISO 200 with my first dSLR so I can't really complain.

And yes, each generation (except for my current one) upped the maximum useable ISO by 1 full stop each time. To me, that's HUGE! Each step allowed me to push my abilities and results a full notch each time. All thanks to higher ISO for the most part.
