I especially like this bit in the executive summary:
Increased numbers of formats for doing the same office tasks do not increase choice in any positive manner. Use of multiple formats increases complexity and ongoing costs. The use of single, standardized formats increases efficiencies and furthers compatibility and interoperability. Choice comes into play in two ways: (a) the choices made by vendors to directly support accepted standards; and (b) the ability of the State to choose among vendors who support accepted standards.
Sounds familiar, doesn’t it?
More to say later, or at least links to other analysis.
