I'll check this out. Be good to know what the sweet spot resolution is for the 100% zoom as then you could optimise images for that - if you needed the zoom in.From the looks of it, a 15MP image doesn't seem to zoom in all the way. Once the iPad 2 comes back home today, I'll put the two to the test with the same image. However, I am able to zoom in significantly closer using two fingers after double tapping, but then springs back to it's "100% Zoom" when I release, same thing happened on the iPad 2. So, including full size images may or may not be beneficial depending on how detail oriented you or your clients are when viewing photos.
