Apple has let go of the PC vs Mac ads and roped in celebrities to promote Siri. As of now Samuel L. Jackson and the lovely Zoeey Deschannel star in iPhone 4S ads which aired Monday night. Its unclear if the brand would be using celebrities to promote its other products. I am anxious to see spoof videos of Samuel using Siri to fight off snakes on a plane. Check out Zoeey after the jump.

These ads were shot by fans from the TV broadcast.
