Rob writes to mention a Computer Business Review Online article on Microsoft's commitment to out-spend Google and Yahoo! on innovation in the coming year. From the article: "Microsoft Corp will spend over $1bn on R&D just in its MSN unit, for the fiscal year starting in July, chief executive Steve Ballmer told an audience of would-be advertising customers. The money, part of the surprise spending package that recently gave Microsoft's share price its biggest single-day drop in five years, comes as the company struggles to catch up to Yahoo! Inc and Google Inc in the search and online advertising market."
