I'm not planning to install Quicktime on my newest computer, and use only older versions of it elsewhere. It's become, as you point out, Raoul, a destabalizing influence. The impact on my ability to view certain content is, at most, a minor inconvenience.

Look at the size of Quicktime, though...some 20 Meg or thereabouts. Compared to many other media players, it's an absolute behemoth. IMHO, like most bloatware, it tries to do *far* too much, and ends up not doing anything particularly well. And sadly, such software usually entertains its own ambitions without regard anything else that might be running on your system.
