This is the most graceful shutdown of a Google product that I've seen in quite a while. Full, automatic refunds for game and hardware purchases, downloads for savegames, and software updates to remove hardware dependence on external servers before they shutdown.

I can't think of much else they could have done to make things smoother for customers, short of not shutting it down at all of course. (And undoubtedly, the fact that they are killing yet another product is inescapable, and doesn't help their reputation for doing that.)
