Agreed I don't see them going fully down but I think soon they will be relegated to the same conversations that follow mention of Windows Mobile OS and every inception will bring only minor improvements if even that.

I mean something as simple as uploads from the onboard memory are not possible on the IOS but my Droid with no mods did it right out the box, and although it may seem small its a pretty big deal in the larger picture. I think as people start seeing these limitations and waking up a bit they will abandon the platform altogether. It will be a progressive process but will only take a few years at most.
