Yeah :/ Unfortunately the app repositories aren't quite up to snuff yet. There are quite a few apps in extras-testing and extras-devel that are probably fine, but they won't be promoted until they've seen some more ...well, testing There just aren't enough devices in the wild yet; I'm sure things will start moving along pretty quickly.
I'm thinking that the vast majority of problems resulting from testing/devel could be quickly fixed with a little work in the shell, or worst-case a reflash, but in reality I don't think the wait will be too long before the useful stuff makes its way into extras (are they calling it 'applications' now?).
