I think this decision further demonstrates that Microsoft is out of touch with their customer's needs.  Releasing a major version of their software in a year and a half, and doing monthly updates of it drives people like me nuts because it shows that the product is unstable.  Businesses want things to work, and work right the first time, not eventually.  If I propose this schedule to the rest of the folks here in my IT department they would laugh, there is no-one available to do monthly testing of these updates, it takes more of my time to manage all these updates, and it has to make the product more difficult long term for Microsoft to support.
