A number of former Nokia employees has formed the Jolla Ltd, who will carry on with the MeeGo OS which was used on the last successful cellphone from Nokia, the N9. Today the company already have 50 employees and most of them have been working with MeeGo/N9, so they know how to make a successful mobile operating system, but the question is will there be other cellphone companies to prepare to use the Jolla software on their phones or not, as there needs to be enough phones pushed out and sold that you will get applications made for the OS (unless you do as Tizen is said to do and include android support).
We hope that Jolla will be successful and we already know they will outshine Nokia when it comes to cellphone OS.
