ah you're right, i forgot about the Android GPL-ness.
If Nokia incorporate some feature from Android into its own WP, Nokia by law are required to make the WP open source,
very unlikely to happen unless MSFT okay with it which of course almost impossible to happens.
Not everybody, I've been thinking of selling my S3 for a while now and going back to using my old N8, but that's partly because the novelty of trying out android has worn off, and partly because I miss
symbian, but like I said, I'm in a minority of users who do miss it
As you said, there is always a minority but Nokia needs more than that to survive.
