After the ill fated marriage with Microsoft, Nokia will re-enter the mobile market in it's own right.

Nokia will be using Android as their OS.  It will be interesting to see how they differentiate themselves from other Android manufacturers.  The Z launcher is pretty cool, but I think they'll need more than that.

I do wonder whether we'll see Sailfish in a Nokia device at some point.  I see some synergy here as Sailfish has been developed by a bunch of ex Nokia employees and the company Nokia is partnering with to produce phones and tablets is also staffed by ex Nokia employees.

Sailfish has been developed from Meego. Meego is a way underated OS and in my opinion would have been a far superior option to Windows Phone.

Sailfish deserves a company like Nokia to get behind it. I wonder the initial use of Android is to get back in the market then introduce a Sailfish line of phones. Sailfish can run Android apps.

Interesting times ahead.
