I think it was two things that made up Nokia's mind. These two things would never be available for any other company so no point in make an example. Firstly, nokia was market leaders with an overwhelming market share. No way they want to sink to One of many Android vendors. Secondly, Microsoft paying them Hugh a mounts yearly during the transition period.

It most have been an easy choice when the destination was made to ditch symbian and meego.

And no, Nokia's straight will not be decided around Christmas. As long as they growing and the have money there is till room improvements.

Android and IOS needed several years to grow.

Let's see what happens when windows 9 comes out and the contracts ends with Microsoft. That is when the call is made. Good, Bad or ugly?

After that change strategy or keep going!
