My intrepid co-worker Matthew noticed this standard button on the Activity Related list. The button doesn’t show on the UI when checked, but appears to indicate a way to compose a Gmail to the Contact in question. Nice.
Update: Google Contacts API was launched yesterday. It would allow Salesforce to google sync for Contacts. Google also released a Google Calendar to Outlook sync product. Openness is a virtue–the best CRM and the best online productivity suite are lined up for a deep integration. Can’t wait to see what gets built!
