Apple Insider found that Safari 6 could officially drop Windows support, especially since information about Safari 5.1.7 for Windows isn't readily accessible on Apple's website anymore and the download has been moved to a support page. So, if you really want to run Safari on your PC, you can still have it if you are willing to go the extra mile. There is no Windows PC version download link on the Safari page anymore.
A quick check with StatCounter reveals that Safari market share remains rather insignificant in the big picture and has stagnated since April at about 7 percent, while the other Webkit browser Chrome has assumed market leadership with 32.76 percent in June. IE was listed with 32.31 percent and Firefox with 24.56 percent.
Interestingly, StatCounter lists Mac OS X market share also at about 7 percent. Even if we do not know how that number relates to Safari browser usage, we can guess that Safari has a very loyal user base on its home platform. In the end, Apple's decision to drop Windows support could simply be a business decision and a way to save money and focus more on the features for the Apple platforms.
