I wrote about this originally on March 14th in Microsoft, When Will Investors Lose Confidence? Technology companies often die this way. Once faith in a platform diminishes, sales lag, investors get nervous, stock prices fall, bad press ensues, faith diminishes... eventually leads to death. Microsoft is probably not beyond the point of no return, but then they seem to have no products in the pipeline that could turn things around. Their one bright spot, business apps (Office and Server), will eventually be hurt by the rest of the business and does not provide a way to bring up the rest of the business. Current management seems to be hopelessly inadequate. I find it unlikely they have more than a year or so to turn things around. It is likely they'll reach some sort of zombie-like status when 4Q13 holiday sales are announced in February 2014.
