Having been heavily into Qt before Nokia, I see this very differently. Nokia had no idea what they were doing with Qt and the Mobilin/Maemo/Meego and now Tizen projects were a farce from start to finish. I'm sure as strategies they looked good in Power Point, but they clearly had no clue how to turn them/it into a credible consumer OS. They very much remind me of the bumbling, bullet point oriented aimlesness of the failed OS projects of the 90s - Taligent, Pink, Cairo, etc.
However, now Qt is in the hands of a company that does seem to understand the technology and has a realistic and executable business plan. That's a good thing.
