Apps updating to use multitasking

I'm happy to report that more and more of the apps I use on a daily basis are being updated to save state/freeze in the multitasking

AngryBirds now just pauses so I can't hot swap over to Words with Friends to play a round (which also freezes so I don't have to go to the load screen every time.)

Browsers are keeping pages open...

Harry Potter holds state...

Gotta find more.
