The only mistake she made that she presumed there is memory protection inside the A\Box. A strict memory protection implementation would block 98% of Amiga programs to run, yet she expected it.
That is just natural for an outsider (and is still a common misconception, many believes that MOS/OS4 will have memory protection, which is true, but not the way these users expect it). I think sooner or later there will be memory protection solutions in MOS, without damaging compatibility, but it's a real hard issue.
