Google might care because they want you running those nice Android apps which interface with Google because that's how they're paying for Android development.
Which Android Apps are you talking about? The Marketplace Apps? The web browser/GMail apps? The YouTube app?
First, Google doesn't take a cut off of the Android Marketplace apps, and they are all actually free right now. Second, the only real ad revenue they are seeing is from people getting on the browser and using the google search engine (given that there is a google search widget on part of the screen, although it is easily removed).
The only real thing the G1 is doing for Google is brand awareness, getting more GMail accounts, and putting a web browser in more peoples' hands (which assumabley they will use google.com to search with and click on ads).
Again, there is no direct revenue for Google here, they are aiming for the horizon and trying to change the game with this device. It is this humble observer's opinion that they are well on their way.
Finally made a slashdot account
Probably should have done this years ago..
Hopefully I can get all my comments critiqued by an undersexed ego-massive of nerdy internet-addicts!
ughh
