And the best of all: It is free to test. Just download the demo and play around with it directly from the LiveCD (or install it on HD). All you ned to test is a little time and an .iso file. the demo is not restricted except it slows massivle down 30min after boot up. Press reset and you have the next 30 time (you can do this as often as you want, you only need to register when you want to use it for more than 30 min w/o the need of a reboot).
Absolutely. If it wasn't for the fact that I could try MorphOS for free I never would have even bothered with it. Within 10 minutes of trying it out I bought a license.
