Untrue for the most part. N9 has much lag in MANY places. Way more than WP7...and I've tried QUITE a few and it takes longer to open apps as well. Have you even used a WP7 phone??? It is much more responsive and consistently so (much more than n9 at least).....but that is not the issue really....it's capability of the platform. WP7 is just not as capable, end of story Please state facts, and don't let your blind hate spread fud.
