See, it is not what me or you prefer personally. I'd like to have Jolla phone with HWKBD, resistive screen, FMTX and hildon-desktop, but this is as relevant as your personal preference. Esp if they are supposed to fight for their place under the Sun. Why do you think the average Joe gives a **** if it is Wayland or X11 and Qt 4.8 ,Qt 5, GTK, OWL or MFC on top of WinAPI? Their target are not the tech savvy guys, but the rest. Having that in mind that move makes absolutely no sense for me. They'll be too late when (and if) they release a device, the same way N9 was too late. And that will happen for similar reasons - we have something ready and instead of trying to make it finished and polished product, we scrap half of it and replace it with something yet to see the daylight. Do you think the majority of Android users have any clue what bionic or dalvik or Surface Flinger is? I doubt.

From technical POV your "preference" might make sense, but IIUC they're not doing some kind of "art for the arts sake", but trying to sell products. That won't sell good if look crappy, no mather the genius that is hidden behind.

And what irritates me a bit is that the "code everywhere" story repeats over and over again. They released SDK, lots of people ported their applications, now what? This is disgusting, sorry.
