Planet maemo seems to be down at the moment, so, to avoid repeatig lenghty posts, you can read my thoughts on the Qt SDK on my The Penguin Moves ! blog. Long story short - it rocks, but it still needs a few magic components (like actually getting to a release phase with Declarative support). Still, it’s way, WAY better for most people than scratchbox. I don’t think it will make a difference in the near future, but it will start kicking serious butt late this year, about when Harmattan gets released.
