I don't know anybody with an Android phone, so I will ask: so you can have a phone experience without ads all over the place? I just assumed that you might have ads here and there, since that is Google's business model.
I don't remember the last time I saw ads on my nexus phone. I think I had an app once months ago that had in app ads but that's the only one that comes to mind. IME they are far from the norm on the phone.
