Want Debian's stable base and Arch's pacman for bleeding edge packages?
Want the security of Qubes OS and Gentoo's portage?
With the correct setup all this can be achieved.
Con No one uses it
It's a very niche OS that no one uses.
Con Small community
It is important when developing to be familiar with tools that other developers use. You can make any utility in any language you feel like, but if it's in an esoteric language that no one can read targeting a small platform that no one uses, then it was just something you did as a hobbyist, not as a developer.
This is not to say that Haiku isn't a great operating system to hack around on. Just don't delude yourself into thinking you're doing it to get familiar with tools that you need to know to be a better developer.
It's still in beta and quite unstable. Making it unsuitable for developing applications of any kind.
Con UI quite different to other OSes
Con Difficulty setting up
Bedrock can be challenging to setup properly with the correct strata.
