The grid of icons thing had been in mobile phones for years and years before Android or the iPhone. What Android borrowed was the capacitive multitouch-style interface of the iPhone.
I played extensively with the Android SDK public releases before it incorporated touch. So did perhaps hundreds or thousands of others. It clearly wasn't going the direction the iPhone was, at the time.
He talks about facts this and facts that. But the fact is, he's wrong. Android borrowed from the iPhone's new paradigms. Has it been that long ago that we've already forgotten history?
Note that none of his facts come from personal experience. They come from dug up videos.
And again, what's the big deal? Everyone's all of a sudden screaming theft. Iterative improvements are good. They promote evolution and competition (eg. one upping each other's designs).
