There's another issue too. It's not just "the iPad is closed, therefore openness is doomed". That would be obviously silly. The problem is that all the powerful forces in our society (barring technology itself) are pushing towards these closed, integrated, proprietary systems. Go look at what ISPs want to do to our internet access! Rather than, as we would expect, having cell phone contracts become more internet-like they want it to be the other way around!
