Microsoft Quietly Ditches WMP for Mac. IE for Mac we can do without, but there's a lot of Windows Media Player-only content out there. It looks like the (third-party) Quicktime components for playing WMP files are free for the download, so that's good. Hopefully that means this isn't such a big deal in the end. (Sounds like some are cheering the move, preferring the third-party plugin to a separate app.)
