not gonna boast iphone, but iphone 5 with lower hardware spec could run on same par or better than note 2.
n i would gladly say that lumia is even better than note 2 with the latest wp8.

n not to forget, the trio (iOS, android, wp8) apps lifecycle are nearly identical. its the efficiency of iOS & wp8 memory management is better than android. period.

if u r talking about battery life, come on dude, note 2 battery capacity is like 2x/3x more than iphone 5 battery capacity. its obviously note 2 will have longer standby time

and i would like to emphasize that Samsung has an extremely bad reputation in their customer service and after-sales service. try ask those ppl that had their Samsung device breakdown n going through the service center, u will noe how their feeling.
sometime i really wonder how can u guys debate without basis and facts.

coz there is no such thing as perfect. everything has a loop hole, and thats y there are always update to patch those holes. even yor android has more loop hole than iOS. wp8 still not sure yet as it still new.

lets be realistic, every software in this world is not perfect, there r always patch and updates r required to be installed. eg. Torchlight 2 has being updated constantly to keep the game bugs in check.
