Agree that enterprise software has different requirements, but Windows Live is specifically Microsoft's consumer cloud product. Sharepoint and a few other products within Microsoft are targeted at enterprise, and for those it may still make sense to be on the 3 year product cycle. However, the hosted version of the enterprise services like Sharepoint and Exchange, targeted at smaller businesses, could be a great place to experiment with new features in a way similar to Google Labs (on an opt-in basis).
