Apple has released Safari 6 for the OS X platform. But the update is not yet out for Windows operating system.
This is unusual because Apple tends to release updates for both the platforms together.
There can be only two reasons why Safari 6 is not out for Windows yet. Either Apple has given up on it on this platform. Or the development work is still ongoing and we would get it in the coming days.
In any case, few people would miss it looking at the market share of Safari browser on Windows!
A friend of mine is disappointed though as he is one of the few who prefer Safari over Chrome and Firefox on Windows OS!
