So first it took over a year for us in Sweden to get paid apps. Then it turns out that there is some bug which prevents "google for my domain"-users from buying Android-apps. Google Checkout with the same account works on a regular computer but not on my phone even though all other features work.
So I have to create yet another GMail address and associate my credit card with it just so I can buy apps which I've been to lazy to do.
Result: I've bought apps on my iPod touch which I never use but not once single a Android app even though I've used Android since the launch of the first dev-phone (2008).
