I'm thinking of playing around with a lesser-used, more obscure open source operating system in the near future to see if I can get all of my work done with it for a couple of weeks. Open to suggestions as to which one to use.

Edit: I should have made this clear. It will _not_ be a Linux distro. More obscure than a Linux distro I've reviewed before.

@devSJR I know ReactOS won't work. Tried it recently and it crashed non-stop every few minutes. And I know Void will work perfectly because I review it about once a year.

Haiku and OI are good possibilities.

@distrowatch I'd say not OpenIndiana, but #Tribblix. Peter Tribble did a great job with Illumos kernel. I used it for some time several years ago and was surprised how easy and straightforward it turned out to be.

@chesheer @distrowatch

Haiku hosts most of the apps which I use including (if I remember correctly) QGIS. It would be better with an automatic login system, IMHO.
Would OI install on a laptop?

@linuxgnome OI should work fine in general, but there might be hardware compatibility issues. First of all, Wi-Fi, I think.
