When did I say that? The improvements in the first (last) year in WP7 were much less then after one year of iOS
That is just your opinion.
No the signs were already there after the launch. It is you who did not see the signs. Your the one here who needs to study more economics. Even after more than a year WP7 is nowhere. You were still wrong with your "2 years". May be you should learn how to read a graph.
Edit: You sound like a Microsoft evangelist (troll), plugging msft products.
