If it weren't for advertising, Google would not have had the resources to develop the Android operating system and distribute it open-source. I don't think advertising their tablet, in the rather uncluttered and unobtrusive manner in which they did so, is unreasonable in the slightest. As it's been said, it's their real estate and they have landscaped it with a little something to help business without losing the focal purpose and attention. Good on them.
In short, to answer the OP's question - yes, you are being too whiny.
op:
if that bothers you enough to the point that you need to bring it up to the world, then i would really hate to see how the rest of your day went...
