I'm a little confused here. I'm not trying to contradict you, I probably just lack the knowledge to understand the problem.

You have your Qt software, it works for you and does what you need it to do. If Nokia abandons it, you will still have it, it will still work. Won't it?

The only issue I see is that as time goes by new hardware will arrive on which perhaps Qt won't work. Is that your concern? That is precisely why I am no longer using Ami Pro, a word processor that for my uses was hugely superior to MicroBloat Word, and if future hardware compatibility is the stumbling block, then yes you have something to worry about.
