Don't be surprised by people saying WP7 is a smartphone OS. In the last months I've read a lot non-sense : - Nokia N9 is not a smartphone because it hasn't WhatsApp, NetFlix, etc; - Android, iOS or even WP7 has better "multitasking" than MeeGo Harmattan; - Symbian isn't and wasn't a smartphone OS, but iOS was since the 1st day.
