This is a companion post to the previous one about Windows without Internet Explorer, which now seems to be possible.
It has been discovered that, once you install Safari 4 on MacOS, you cannot remove it. The only backwards route is to reinstall the operating system from scratch. This is a seriously BAD THING. Microsoft got a lot of stick for embedding IE deep into Windows so it could not be removed (possibly not deliberately, but as a consequence). There are many reasons that you may wish to remove an application—shortage of space is only one. It was possible to remove the Beta versions so why not the real thing? It is possible to remove Safari from Windows.
Apple Safari takes more resources compared to Opera and Firefox. sometimes it also freezes so i would still stick to Opera.
