I took the "size matters" approach and voted for the E-410, which superficially makes no sense because I bought the E-510. I "needed" it last summer for a major trip, in which I wanted a smaller and more modern camera than my E-1. It did a great job and I love the IS, and would not (did not) want the E-410.

...but now I have the E-3, which has all of the features that the E-510 does, and then some. So if I choose to carry the 510 instead, it's primarily because I don't need the additional capability as much as I want the smaller and lighter body. Honestly, if I could swap my E-510 for a E-410 in similar condition, I probably would.
