My mind isn't made up, but I'm more inclined to believe MorphOS is the real deal.
1) It will be 100% PowerPC native. The 3.x compatible libraries are native. I have lived through Mac OS's 68k to PowerPC transition, it was painful. Mac OS X was less painful because it was written from scratch. On this basis I'm more inclined to use something built for a new platform from scratch than a port.
2) The only thing running on the A1 is ExecSG which is useless on its own. I think people are far too optimistic regarding how long it will take for the complete OS to be ported. Even when it is there is little telling what percentage of the OS will be native. MacOS was LESS dependent on specialized chips than AmigaOS and it took many years for a fully PowerPC version to surface.
Switching between 68k and PowerPC contexts isn't costless. On paper I expect MorphOS to be faster on similar hardware.
Anyway, I already spent a lot of money on the 'establishment', a PowerBook Titanium. I won't be able to buy new hardware in a long time.
