MSNBC and Apple
NoneIf you use a Macintosh and visit MSNBC you'll discover that you are not able to utilized their website. All the video content checks the operating system and will not play the video if you are not using a Window's system, even thou Windows Media Player is available for the Mac.
I was also getting errors when I was clicking on several news links. It appears that MSNBC is using some special HTTPD redirect commands that are not industry standards.
This isn't a major issue since there are lots of sites that offer news on the Internet, but it just goes to show how Microsoft tries to force people to use their technology even if its not the best.
