While you're waiting for the E-7...
...you may like to try this: Photo Ninja 1.0
I've been playing around the with this new RAW editor, which follows on from Noise Ninja. I've been doing this digital stuff for quite a while, and tried pretty every RAW app on the market, but this one really surprised me.
I wrote a little piece about it here ( http://www.snowhenge.net/pblog/article/iced_by_photoninja ) and uploaded some processed images, but really you need to try the demo.
ymmv, of course, but to me it really packs a punch.
