So about once a day I get an email from a partner asking for information on a competitor. Did you know we actually have a consolidated location with all of the competitive guides in it? https://mbs.microsoft.com/partnersource/sales/marketing/competitiveinformation/playbooks/ is the link. The page lies though... There is a salesforce.com playbook available here.

Just a reminder, these playbooks are partner confidential, which means you are not allowed to share directly with prospects. (I use them as talking points and nothing more.)
