I wouldn't bother arguing *LTD* about this. Many have tried and failed. He simply refuses to accept that Redmond has produced some quality products without ripping off Apple. Each versions of every Microsoft products have their +'s and -'s. Recently, with Windows 7, Office 2010, IE9, WP7; Microsoft have been churning out some quality, solid, software. Not to mention what a great success the Xbox has turned out to be. Yes, they are not always the first to have some features in their products, but neither are Apple at times. Fast user switching is one that springs to mind.
Just because they licence their software to a range of hardware companies, *LTD* automatically thinks they are trash. And, yes, some of their products have been trash. But so have Apple's at times.
