Seems language barrier at work here. I should have better written "limited usability" instead of "limited use". The Efika 5200B has a 400 MHz CPU and 128 MiB RAM. This should sufficiently illustrate the "limited usability".
The iBook and the PowerBook are the only mobile devices supported by MorphOS, and the PowerMac G5 is the fastest machine supported by MorphOS, so that's why MorphOS for them is in the most expensive category. At least that's my personal explanation, and I don't speak for the MorphOS team.
