Quoted from jar155:
If the boards were reliable and reasonably priced, people wouldn't care so much. But they're expensive and faulty. Also, the unique revisions of boards for specific games is problematic for several reasons.
The system wasn't ready for release, which is evident by the high failure rate, the lack of documentation, and the constant revisions between games.
Are people really getting raked over the coals on replacements for these "defective" boards? Stern's tech department has always been pretty generous in my experience.
