Are you joking? I mean you link to a study on Microsoft.com! Not even mentioning Microsoft's history (particularly the incident when they showed internet explorer is faster than Netscape when Netscape is on a slower connection!). Also it is talking about file access only... AND what about Microsoft's wonderful "total ownership of windows is less than Linux.." which is just funny.. really is funny...

Not to mention this is testing Samba not linux. And even then only one feature of Samba.
