I think apple cupertino Geek Developers...come to work and say to each other....nothing is broken...so lets fix it...prime example is iMovie....there was NOTHING wrong with previous versions but they decided to do it over anyway....I spent a long time doing a project on latest version only to see it deleted when I got a message saying the MacMini needed to be restarted....there was NO save, or save as in the menu....I looked...how could then forget to put it in.....I think most of them flunked LOGIC 101 in college if they went to college and it makes me angry.
