I can vouch that MorphOS is good enough to use and not wish you had OS4 instead. I have no plans to ever get an OS4 system so long as they are priced the way they were the last time you could get one.
MorphOS does everything it can do, and I would say just as well if not better in areas too.
Who made this new board? Is it another Chinese company that someone licensed to have boards made from a design, then plan to call it something else and charge 10X the price for?
