FG - you left off all the examples for video - IS is massively useful in video to reduce shake and vibs when hand holding or even using a steady cam rig.

The new version of IS is useful for faster shutter speeds as well (As per Bryans review) and IS is very helpfull just for aiming at high magnifacations. Most shots are best in early morning or evening because of the sweet light, broad daylight shots are for the most part not ideal lighting and cloudy is much better than broad daylight.
Never mind just hand holding!
While I would love to have IS in the 24-70mm II as much as anybody I can see myself getting around it FAR easier than a super tele.
