Well, to be honest, it wouldn't be all that useful to transfer the data if it's one-time and one-way. I'd ideally like to be able to play on both my phone and my tablet with the same set of data. But I suppose that's entirely unrealistic, perhaps even with a rooted phone...
My phone is a Galaxy Nexus running Android 4.2, and my tablet is an Acer Iconia running Android 4.1. I'd like to update it to a newer version, but for some reason the updater says there's no newer version available. I wonder if 4.2 isn't compatible with my tablet for some reason? I find the latest release of Chrome to be quite buggy on the tablet, so I have to use the shipped version, which is a bit out of date. And the battery widget which works fine on my phone doesn't actually show the battery level on the widget itself on my tablet, only on the notifications bar...
