Well ok how bout this. Qt libraries are currently compiled for the ARM architecture. We are fairly certain that the meego first device will be an ARM device. WE KNOW that meego is going to be a Qt based platform (as far as GUI/APP goes). You can already download and run Qt apps on maemo. So what we end up with is the fact that Meego will run on the same architecture using Qt which is already fully functional on the N900. Hows that?
...I'm not a programmer, but what I read is that an app that is developed to run on an x86 netbook, a quick recompile and a tweak or two later, it's up and running on my N900, right? IMHO, we're talking about a netbook with maybe a similar UI, but 1024x600 screen. Depending on the app, there may be quite a bit of work converting from 1024x600 to 800x480 as far as layout, then usability becomes a question. To me, at least, this entails a lot more than a quick recompile. So to me, while I can see some benefit of QT, perhaps the "stock" answer is overstating the benefits a bit. And once someone starts thinking they may have been lead astray (even if slightly or innocently) they start questioning the rest of the points....
