Just wanted to know if it's worth trying out.
You should tell first what you expect.
In term of features, Minix is more or less equivalent to what Unix was 25 years ago. It's main advantage is the tinyness of everything, but don't expect any modern application, hmm, any application to be available ...
That said, I think I'll download it and have a look at it, maybe just to remind me what I used in 1989 on my Atari ST (1 MB of RAM, 8 Mhz CPU, no HD, 720 KB floppy ...).
