Quicktime is evil plain and simple.
If it were a simple player installation that did not take over your system trying to play every damn file your browser finds I would not have nearly as big as a gripe about it.
But nooooo...they have to just take over every damn thing with a really crappy player. MP3 file opens in a full window to play? Oh that's how Apple does it because they are allergic to multi tasking!
If there would be one thing that Microsoft could do (all in one) and nobody would complain about is their media player. If that truly played everything including quicktime stuff - it would be great!
I have a Canon SD780is point and shoot that takes great videos for a TINY camera. They are quicktime and do play without QT installed BUT to edit them I need QT files. QT alternative does work here but it's a joke that this cannot be bundled with Windows out of the gate.
