IE7 leaked?!

According to an article from PCPro.co.uk, the latest version of Microsoft's web browser, Internet Explorer 7. This version was not intended for Windows XP, but for Microsoft unreleased Operating System, Windows Vista.

From the article, "The screenshots certainly seem to show off the many new features expected of IE 7, with items such as tabbed browsing clearly visible. Likewise a number of the under-the-bonnet changes are also shown on some screenshots, such as the ability to delete browsing history."

It seems as though Microsoft has to keep up with Mozilla Firefox now with tabbed browsing, although Microsoft's security and management product manager Ben English has been noted for saying that features such as tabbed browsing are not important to IE users (ZDNet News).

Since when does Microsoft know what its users want?
