Is this worth getting upset about or not?

I think this a PR push by them nothing more. They know that it will attract attention and people talking up/down thier products costs them very little. A gamble I'm sure they weighed prior to release.

I agree with the realnapster- Its an advertising gimmick to drum up business

Personally I dig it, I love Starbucks' approach to advertising. It is brilliant, instead of shoving millions of tv commercials down your throat they're more passive aggressive about it. It is much like when they did the magnetic coffee cup thing in several different big cities.
Besides, what is wrong with making people think? *gasp* Nowadays people don't use their heads much, Starbucks is just rockin the boat
