Youre free to disagree just for disagreements sake. But youre incorrect.
Yourre saying that Canon made the 24-105 IS because of the long end and not the 24mm end is preposterous. News flash: Canon made the entire zoom lens an image stabilized lens. What was Canon supposed to do? Suppress image stabilization at some point between the two extreme ends of the included focal length?
And for the 24mm end, you don't think IS makes that much of a difference? It makes a difference. Particularly when you realize that the wide lens essentially condenses a scene and, in doing so, produces diminutive detail within that the photographer just might want to be sharp while not having to carry a tripod around in order to attain it. Its the kind of result that viewers can appreciate when they see a giant print made and placed on a wall and they get blown away by how much content is clear and crisp when they walk up to the print.
Where all this tends to fall apart is when it's being applied to a phone camera, which by its nature and physical attributes is hamstrung to begin with, so that any hype Apple infers is sort of like a feature without a benefit.
