The point was that it's so wastly outdated that pretty much any device made today
that has a native compiler available is a better choice as far as Qt-fication goes, the only possible motivation being if you actually have an N8x0 gathering dust and too much time on your hand (and as post-Qt4.5 on Diablo never happened, apparently that's not motivating enough).
... I would disagree on the basis of webOS' official support for SDL and OpenGL applications. If that's OK, Qt has to be OK, too.
