If you're asking about OS GUIs I still use an Apple Mac and still find most others pretty clunky in comparison.<p>If we're talking software applications I loved the way "Videoshop" and "Futuresplash" worked in comparison to their competitors and that still holds true today, and the Mozilla web browser around 1998 still stands out as one of the worst I've ever used.<p>If we talk cars, the `61-`63 Ford T-Bird is still mighty impressive.
