What do you mean? Since I don't see any point in using a MorphOS machine for watching video flicks or browsing the web (I have plenty of other systems that do both so much better, like 99$ apple TVs loaded with XBMC), and native productivity software for MorphOS is a rare thing, I tend to try out old AmigaOS gems on it. That quite often ends up with lockups. At the end of the day, UAE on my quad core xeon is much easer to work with. Can even run multiple UAE instances at the same time, and reboot time is 2-3 secs, not 10.
I suppose if UAE satisfied my needs I'd be able to resort to similar solutions.
Right now I have OSX, Ubuntu, and MorphOS (as well as three Windows computers) and I get the most use out of MorphOS.
And I don't know what you're doing wrong, but I rarely have lock ups.
Those happen to me more frequently under OSX and Windows.
Still, if you're not using it, then I guess you don't need to pay for the license.
As I've stated in past posts, I'm ready to pay for licenses on a Powerbook and a G5 Mac when support is ready.
