Safari 4 Beta Review

Whenever Microsoft integrates features from Mac OS into Windows, the Apple fans cry foul. "It's a ripoff!" they say. "Apple did it first!" Likewise, fans of the Opera browser are perpetually claiming Firefox ripped them off.
Nobody but historians and fans care who did it first; users just want to know who does it best. And copying the other guy isn't cheating. This isn't high school. Copying the competition is how the free market works.
Companies improve their products by stealing ideas from the competition and improving them a little bit. When we see companies doing that, we shouldn't cry foul -- we should pat them on the back and say, "Well done!"
