I'm not sure why people assume that Microsoft only makes money on Windows and Office. There were 11 separate businesses within Microsoft that brought in a billion dollars or more in revenue last year: http://techflash.com/seattle/2010/07/microsofts_11_billion-d...
Actually, I don't think you understand Microsoft's business model. "Server and Tools" may only generate a modest profit of only a billion dollars per quarter, but it is the foundation of all those Windows sales. The real core of the company is not the end-user stuff, it's .net, Visual Studio, IIS, and SQL Server.
If you're actually trying to arguing that MSN/Live/Bing has been an endless waste of money, then of course I'd agree.
I admit that S&T was an oversight on my part in my OP. But MSN/Bing/Live, various attempts at tablets, phones and all sorts of other doodads and geegaws have been money sinks.
