"Microsoft Corp. has commissioned a study showing that its .Net development environment is more productive than comparable Java environments, a top company executive said at the VSLive! Orlando conference here. Microsoft Developer Division Corporate Vice President Soma Somasegar said Microsoft commissioned The Middleware Co. Inc. to study productivity and performance comparisons between Microsoft's Visual Studio .Net 2003 and IBM's WebSphere and other tools, and Microsoft fared significantly better."
Nice, but it's a pity that an independent researcher didn't find this out without MS petitioning them to.
