Note you can change the ISO without ever hitting the ISO button, as far as I can tell the ISO button is designed as a backup option to using the Quick-Nav.
... which is the wrong design philosophy, because that requires you to take your eye off the action and look at the screen to invoke the ISO adjustment on the Quick-Nav and then scroll to the correct setting. A dedicated button is preferable for settings like shutter speed, aperture, and ISO which must be changed all the time. (well, ISO wouldn't need to be if Auto ISO worked in M mode)
I'd generally agree, but only Canon seems to have found a really usable location, Pentax's overloading of the OK button would work too if the K20D had permanent in-finder ISO display
And the ISO button is FAR better placed than on the Nikon's, where it's both awkwardly placed and indistinguishable by feel from the buttons next to it (WB and Qual on the D300). I prefer the Sony layout in this case, but Canon did it best on the 5D/x0D series.
The Nikon ISO button location isn't ideal either, but I find it more accessible with less hand contortion required and I find that it *is* distinguishable by feel because it's on the bottom right corner of the WB/Qual/ISO button "triangle".
In any event, Nikon's Auto ISO works in M mode, so I don't have to change the ISO all the time like I do with the Sony.
I find the Nikon location worse since I have to change by grip on the camera completely to use it, which for me really means taking the camera away from my eye anyways, and I never can distinguish the bloody thing by feel. At that point, using the Sony Quick-Nav is quicker since I'm already looking at the right display. Nikon's Pseudo-TAv mode with Auto-ISO in Manual is OK, but I usually find it somewhat problematic as it behaves differently in Manual than in other exposure modes (Normally it won't drop below my set ISO, it does in Manual).
