Kit zooms are what their target market wants, I think...
I think you are right. That said, for me, the EP-1 and so forth are not the camera for a zoom at all. I did get the kit with zoom at first for 2 reasons, I figured a zoom would be useful, and I gambled (and won I think) that the Panny 20 is better than the Oly 17. With the Panny 14 coming out soonish, my EP-1 will be a two lens kit and nothing more. Perfect for me, small with compact lenses. No, not a CLE replacement, but it can do the same job.
