My dialup is still goosed so couldn't upload over the weekend but this is from my 2 and a bit month old 40D before I cleaned the sensor:
I don't think there's any need for a bigger pic so you can cringe at every spot of dust on there I think the big splodges are stuff on the lens which I've also since cleaned. Pic taken at an effective f/96 BTW.
I guess without the anti dust there might have been a few more specs but from what I've seen so far the Canon anti dust feature is doing next to nothing for me and was one of my reasons for upgrading My 300D was just as dust prone as far as I can tell.
