Just came across this.
Now Google Apps premier users can avail of the famous Salesforce CRM, at a nominal price of course. Its an alliance of sorts to stave of the big bad monster from taking on the individual firms. To be honest, it is a one place solution for a lot of SMEs for a simple and yet effectively managed enterprise system.
Effectively, Salesforce and Google Apps are combining their users for a joint Go-To-Market, adding more value each other's product offerings. De factor internal messenger for this would be the Google Talk gadget, which works like a charm.
For Google Apps basic users, who know that paying $60/user/year is slightly over their IT budget, they can use SugarCRM which comes absolutely free of cost!! Knowledge of XAMP is solicited before going ahead with SugarCRM.
