Regarding the talk of Nokia applying their own UI to Meego. Perhaps I'm missing the point, but surely Meego is all about the UI? The aim is to have a UI that crosses devices, meaning that you have applications that use the same UI whether on a phone, a netbook, in your car or in your toaster.
The actual Linux distro behind the UI is meant to be interchangable; debian-based, red-hat based or whatever. So if Nokia changed the UI then that would be entirely defeating the purpose of Meego.
We would end up with a similar situation to Android/Symbian, where there are incompatibilities between different phones running the same notional OS because of the wild differences in the UI.
