Nokia will make Qt available under GNU’s LGPL. Qt is a cross-platform toolkit, which has powered various applications on the desktop and mobile. The LGPL will encourage its adoption especially in the mobile world. I also think that Nokia itself will do many more things with it for its own purpose.
Qt is highly portable across multiple platforms, but there aren’t many applications which exhibit that. Does Qt have many users which use multiple platforms? In my opinion, other than KDE, Qt needs to exhibit more, smaller applications that end users can make popular. I look forward to using more cross-platform tools powered by Qt. Maybe Google Chrome could have used Qt and be ready for multiple platforms.
