Very excited to see what Google has in store. Although I do wonder why they are requiring persistent icons with apps like that now. I do understand that it prevents apps from being killed but the icon is annoying. They should find a way to fix this so I can run apps like Sidebar and RoundR without the annoying icons and risk of being killed.
