little disappointed by what you are writing. Is it really so unstable ?
No, it is not unstable. The firmware seems to be a bit picky about usb sticks. My older usb sticks work with the firmware, newer don't. Once MorphOS is booted all my usb sticks do work.
MorphOS works fine on the Efika. The hdd is slow (but with a flash memory it is conveniently fast for normal usage), teh RAM issue is an issue, but IMHO not as bad as some may say. OWB works nice on the board.
But I would only recommend the Efika if you either want to have a ultra low enrgy and 100% silent system (my Efika system draws 14W with 128 MB Radeon 9250) or your main purpose is to tinker around (cafting a case, do seldom things...
If your main purpose is to *use* MorphOS w/o hassle a Pegasos, Mac mini, PowerMac or eMac may be the way to go.
Best is to have an Efika for toying around (and as fall back system) and a G4 for everyday use - at least that is my approach.
