Qt LGPL: 250% Increased Demand New licensing Support offering for LGPL users Qt Downloads from qt.nokia.com Qt

© Nokia Qt licenses support all business models *Runtime charges apply when the Qt-based application is part of a joint hardware and software distribution and the main UI of the device is controlled by Qt.

© Nokia The virtuous cycle Increased use of Qt Larger Qt ecosystem More feedback & contributions Faster pace of innovation = a better Qt Open Source Commercial

Qt applications will be commercially deployable during Q and preinstalled in devices later in Qt will also be made available to the Symbian Foundation. Qt provides the Symbian development community a new developer offering with improved productivity and developer fun. Qt is the basis for a facelift of applications and the implementation of a new Symbian UI style.

© Nokia 2009 Community rules: Nokia want to learn from their success Nokia want to continue to build the strong track record of Qt. That's why Nokia acquired Trolltech Nokia will sponsor people and projects Nokia is and will be even more active in various areas: - KDE, Linux kernel, X.org, Mozilla, supporting FSF etc. Nokia and Open Source
