Thanks, I am mostly curious since I am not a developer, but before buying my N900 I have only heard about Qt but didn't imagine it could have great potential for cross-platform development & deployment. I read on this forum that Maemo 6 will be entirely based on Qt and Maemo 5 already has it on beta stage, but my technical skills on the subject are not enough to evaluate if all applications based on Qt will be easily ported between Maemo 5/6 and Symbian. If this portability turn out to be true it sure will be a great play from Nokia, and they will be able to give Apple Store a real strong competitor.
