What other operating systems have you tried so far?
It is most likely that everyone of you has tried at least windows and GNU/Linux, but what other OS's have you tried, especially free ones? Maybe you could also describe your experiences with them.
In all my life I've used windows 98 and XP, Mac OS 7.5 and then all the GNU/Linux flavors, but I have also given BeOS 5PE (Personal Edition) a try too. There is now a free BeOS-like operating system being developed for some time already which is called Haiku OS that looks very promising and I can't wait when I'd be able to use it.
BeOS leaves us an awesome heritage and it still lives through Zeta OS by Yellowtab which is a proprietary OS and more importantly Haiku OS which is Free Software, but attempts to retain all the best things that BeOS had which can make it an OS of the future.
