It's a very lightweight single-user OS with an excellent GUI and a Posix command-line environment (i.e. bash, make, gcc etc).
It's not a server OS, and it's not particularly secure, so it's not a particularly good choice in any environment where it's faced with the outside world: it assumes that you own the machine, trust it, and control what software runs on it. Remember it came out of the DOS and Win95 era.
But it's really good at giving you a comfortable Unix-ish development environment on old Pentium-grade hardware which Linux struggles on.
Watching the 97 demos of multithreaded gui and decoupled subsystems (could change rendering parameters on the fly for each different screens) I was as sad as moved. Quite a peculiar bit of history.
