"We’re naming the next version of Android after one of our favorite chocolate treats, KitKat. Look for specially branded KitKat bars in a store near you that give you a chance to win a Nexus 7 or Google Play credit."
This is a tiny bit embarrassing for Google, honestly.
I don't see anything, whatsoever, embarrassing about it. It sounds like they're having a bit of fun with it, and why not?
But really, imagine if Apple called OS X 10.10 "Pepsi" and you got a free upgrade with every Pepsi you bought. It just feels… I dunno, it feels kinda corporate and sketchy to me, and I think others as well.
I don't really have a problem with it though.
Android Lion
Android Mars
Android Nuts
Android Oreo
Android Peppermint Crisp
They'll have to introduce their own brand of chocolate after that.
