I don't exactly agree on this, for two reasons.
First, porting the software which people can already use elsewhere does not make Haiku more interesting than other systems. We do need native apps to show what Haiku can do better.
Second, badly integrated ports are quite against what we try to achieve with Haiku, that is, a coherent system where everything just seemlessly blends in. Ported software which stands out too much (by behaving or looking slightly different from native software) easily ruins that experience.
That being said, the Qt port seems to go a long way towards looking and feeling like it is native thanks to 3deyes and Diver's efforts. I look forward to see how far they manage to get it and wether they hit some limitations in Qt or not.
