My finger is touching the end of my nose whilst my other paw is pointing right at your list. Spot on. Although, I would add a 5th element which is that Nokia also needs to provide competitive hardware support such that they're at LEAST as good as their competitors (replacement parts, repair and service locations as well as presence in stores so that their hardware is sold in a place where you can return it if you need a replacement right away, standard ports, etc.)

If they don't meet at LEAST the openness and support, then they're no better than anyone else. You would have to weigh their competitors against Nokia and find Nokia lacking or at least not any better.

So wait--what happened to open-development? I remember sometime back when I argued about how Nokia wasn't very open-sourced because of mountains of closed-source and locked dependencies, someone tried to argue something along the lines of, "Yeah well.. Nokia may have a lot of closed-source in Maemo, but they have a lot more open-development.. and THAT'S what matters!"
