No money, maybe. Free cross-product advertising, definitely.

I'm not sure whether the fact that (allegedly) no money changed hands makes this whole thing any better. I've never been a fan of Android or Google because I'm allergic to advertising and that's basically Google's business model, but blatantly signing cross-promotions deals like this so not one but two companies can leverage a new phone OS release to spam the internet with free advertising doesn't make me feel any more positive about Google and Android. But I guess I'm a lost cause for them anyway...

Trademark infringement -> no money changed hands. Smells like a huge pile of bullshit to me, but I'm certainly no expert.

In my entire HN history I have never seen a sentence and a link posted more than this "no money changed hands" one.

It's one of the most important sentences in the history of HN.
