Really interested in this lens. A girl I've sort of been dating does a lot of birthday parties in hideous, hideous light. She isn't very strong and a 5D2 + 24-70 + 580EX II is actually a lot for her to handle for a couple of hours. I know that for all of us he-men, slinging that around is nothing, but when you don't have a lot of strength, camera shake becomes a problem.
So... I just don't get why anyone would be against IS. I really don't. Maybe YOU don't need it, but there is a lot of insinuation that you must be some kind of crappy photographer to want it. Sorry, but my girl isn't a crappy photographer; in fact, she's a fantastic photographer. She just has a model's build and she could use a little IS in low light to keep from having to throw out a lot of blurry photos.
Can't wait to see the reviews.
