Don Reamey has a nice blog about Mendocino. He basically talks about IBF but as Mendocino is extended IBF most of the things that applies to IBF applies to Mendocino as well. To be more specific Mendocino is designed to provide the SAP backend a better and user friendly UI so that user doesn't have to move from Outlook to IE and vice versa. Mendocino works with Outlook only and provides much more functionality than IBF. It certainly does effect the productivity of information worker. Anyways keep reading the mendocino news. Will post more later with something technical  :)
