Apple released a minor OS Update today… so go launch Software Update and get yourself a bunch of update-y goodness. And another iTunes Music Store milestone….

The iTunes Music Store sold its 50 millionth song last Thursday afternoon…something by Sara McLaughlin if I remember what I read in the press release correctly…. and that 50 million does NOT include any of the songs downloaded as part of Pepsi’s 100 million song giveaway! Not bad for a music store all the ‘experts’ keep saying is going to fail…

For comparison’s sake.. the most recent numbers released by Napster show that it has sold 5 million songs…. which is what the iTunes music store sells in about 3 weeks (something like 1.3 million songs/week at the moment for iTMS)

Here’s what’s new in 10.3.3:

The 10.3.3 Update delivers enhanced functionality and improved reliability for Mac OS X v10.3 “Panther” and is recommended for all users.
