Internet Explorer 9 (IE9) will be available for download from Microsoft’s servers beginning at 9 a.m. PT Monday. IE9 follows its predecessor, IE8, by two years, a slightly-shorter cycle than the two years and five months between IE7 and IE8. Microsoft released a public beta of IE9 last September, followed that with a “release candidate” a month ago. Microsoft’s IE9 has yet to make an impact on Microsoft’s global browser usage share.”]
