Today Nokia presented the future of nokia and its software platform. Qt app development will be the focus for Nokia which will be the framework across both MeeGo and Symbian. Nokia will also develop its own future UI applications using Qt.
The planned and future development of the higher layers of Symbian OS itself will be based on Qt; Nokia states that it will "allow a continuous improvement of the Symbian experience" and, critically, will be compatible with the existing Symbian^3 platform and devices. This confirms that all S^3 systems (nokia N8) will get future updates and UI improvements planned for S^4. From now on Nokia will refer to Symbian instead of S^1,2,3,4.
Nokia highlighted Qt's robustness and status as a tried and tested framework, together with its ability to quickly create rich, intuitive and visually attractive applications.
It seems Nokia are busy at work reorganizing their strategies!
