I've heard this comment about the 1/3 stops previously, I can't prove it on my 20D cos it only has full stop selections

The reason they started putting 1/3 stop ISO's on DSLR's is twofold IMO:

1 - to give you the chance of accurately altering exposure using the ISO - if you want a particular shutter speed/aperture combo you effectively have ISO priority.

2 - A sales/marketing ploy to 'give you more' when you purchase xyz model of camera.
