Wrong.

Nokia announced they would abandon Symbian and MeeGo and then started selling WP7 phones. They killed their cash cow (Symbian) with nothing to replace it but an unwanted product.

Killing off Symbian is the direct cause of the 70% drop in China sales.

By analyst estimates (Nokia won't release the real numbers) the N9 outsold all WP phones in Q4 2011 even though it had no access to the US market.

Elop needs to go. Even if you wanted to kill off Symbian and MeeGo you don't announce plans to kill off Symbian and MeeGo until you have sufficient sales in your new line.

What Nokia should have done is added WP and Android to it's offerings, invested in MeeGo as a possible break-out exclusive OS like iOS and continued to support its huge Symbian base. It's called risk mitigation and opportunity readiness.
