Apple has used celebs for their commercials for over 15 years or more. Get over it.I like Bill Hader and the commercial is alright.... but I don't care for Apple using celebrity endorsements. I feel it cheapens the brand. I'm supposed to want this product/service/etc... because some random comedian is on a commercial?
At least they are showing off a semi useful feature (though reading emails is way easier and quicker than having them dictated)
The direct objective is to entertain you. Not sell you a specific object.
