If you look at some of those, he was right if you extend the timeline out.
"nobody wants a mouse" - True in the days of touch screens. "the mac is dead" - Becoming true as they continue with the hardware choices for their pro lines and iOS'ification of the MacOS.
"ipod is a niche product" - It is now for those who just want a music player and not a phone.
"apple watch's a flop" - That was true when it came out. Apple was expecting it to be far larger than it was. Its now starting to gain traction, but don't see it growing to the number users who have iphones.
It might be better to say he was ahead of the curve on many of his statements.
