My buddy Terry White put it perspective for me. He said, Imagine a kid going to his parents and saying I need a hundred bucks to buy Elements to fix the photos Im putting on my MySpace page. Now you know why Adobe created Express, and who its made for."
It's not even good enough for that. As a test I just uploaded some photos of some stuff I'm going to sell on eBay. I shot them using a towel as a background. I figured I'd remove the towel and back the background look totally white. This is not hard using even an old version of PS Elements. It is impossible using this web based thing.
To put this another way, no one who has iPhoto will want this. iPhoto is a much more capable photo editor. So as an editor it is of no use to anyone who owns a recent Mac, as they all came with iPhoto.
But now the good news: 2GB of free space for hosting images on the web.
I think this was intended to compete to Google's Picasa
