Wow. I didn't expect that much answers. Thank you all for your insightful replies.
The weak GUI is likely caused by the fact that most core developers are cross-compiling from Linux. For short tests a GUI with all whistles and bells isn't that important.
MUI lacks some features because we have to rewrite everything from scratch while MorphOS team has access to the MUI sources.
Stability: the Linux-hosted version is quite stable, so it must be the native drivers which cause troubles. I'm assuming that driver development is quite difficult because of the amount of available hardware and there is no native debugger.
Okey, we are a bit behind but you can already feel Kitty's breath :-)
