Personally I've had little luck with even running XP applications on Windows 7. More generally, going by the difficulties experienced by many companies and organizations in the transition from XP->7, it's hardly an isolated problem. Perhaps Windows maintains the best backwards compatibility of any mainstream OS, however I would hardly describe it as "mythological".
