Is it? Dunno, I never installed it :-) The point still stands though, there are all sorts of "non-free" applications whose authors might not be willing to rewrite from scratch in a different language.

A related issue is ports of existing upstream apps (which for obvious reasons are extremely unlikely to even consider switching). Goodbye Pidgin, Gpodder, Abiword, Gnumeric and so on unless/until "the community" manages to port Hildon to Harmattan. Anidel has already indicated that we'll lose Xournal, and I can't blame him.
