People are thinking about moving to Android because it is fast approaching the point where it provides all the features that they want, and there are a number of compelling devices to choose from. Contrast that with the situation at Nokia, where it takes forever to deliver a single device that has been talked about for months, and even then they make a complete hash of it. Nokia couldn't run a piss-up in a brewery.

Most people will not throw away good money on a device simply because it runs FOSS. N9 doesn't really have much of an advantage (if any) on that score, anyway.
