The main thing which strikes me as smart is the Android Market web store.
At long last Google recognises the app store model is broken and they are shattering the model by opening a web store. You can now browse the store using a browser of your choice and when you choice to buy an app, its sent to your phone or tablet. Just the way it should work. Heck you can even using links point to your favourite apps, comments, etc. Genius!
This means finally developers can link to there app and join it up with there own support forums, etc. This thankfully has to be the end of the app store model. And I for one, am thanking Google for killing the model dead!
