Amazng! I was just about to come and write this same as a review suggestion.
Have a minor OS smackdown: benchmark Haiku vs. ReactOS vs. Minix 3 vs. Plan 9 vs. Debian/HURD vs. Debian/Linux.
I'd love to see it, since all of those aforementioned ones claim to be better than anything else on the market. Some 7zip compression tests should be doable, at least.
