From Apple's news page:
500,000 Safari Downloads
Users have downloaded more than 500,000 copies of Apple?s new Safari web browser since the free public beta was posted on Apple?s web site. [Jan 10]


Ha. One way to ensure you have tons of downloads is to release something that's not quite ready for a worldwide test to a ravenously loyal customer base and include bugs so dasterdly (sp?) that all 300,000 of those guys needed to download the thing again before the end of the week. Looks like word's gotten out to 200,000 so far.
