I have a reversi game on the App Store called 'Ultimate Reversi'. A few months ago, Apple received a C&D letter from Ravensburger and asked me to resolve the issue with Ravensburger or remove my app from the store. Ravensburger has a 1981 trademark on the Reversi name registered in Germany and extended to Europa in 2005. As it is the original name for a 19th centuary game, the trademark probably wouldn't hold in court. Because Ravensburger targeted Apple instead of me, I cannot tell them to go fuck themselves so I eventually ceased and desisted.

...And every processors which supported Windows had little endian capability (Intel was always little endian, Alpha had both capability, PowerPC was natively big endian but little endian was added to make Windows portable on it. Little endian support was dropped on the G5 (this is the reason why VirtualPC didn't supported the G5). So this would be a nearly impossible job for Microsoft to rewrite all their code produced for 20 years to make it endian-clean. We will probably never see Windows on a big-endian architecture. (although Mac OS X is probably endian-clean, at least Darwin is).
