For this same reason, however, both would do better to invest in Firefox, the "Linux of browsers." In some ways, the browser efforts of Apple and Google are much like the Unix efforts of IBM, Hewlett-Packard, and Sun Microsystems: they threaten to splinter the browser counterattack on Microsoft rather than solidify it.
So, just to make sure I get this straight: Internet Explorer has been losing share to Firefox, Safari, and Chrome—three open source, standards-embracing browsers built on two frameworks—and Microsoft has been forced to enhance IE significantly in IE8 (better standards support, better privacy, better performance). Firefox is winning. Google and Apple are winning. And, thanks to competition and choice, IE users are winning to.
So, the solution to this non-existent problem is less competition?
