Running a business? Well, there is no better base than Google Apps to kick things off. Email, Docs, Contacts, Calendar, plus integration with the entire Google Apps Marketplace, GA really covers it all.Plus, everything is online ("in the cloud") and easily syncs with all smartphones (not sure about Blackberry, but I'm excluding them).Manage multiple domain emails from your core account, and/or manage multiple accounts via Groups (eg. info@, contact@, etc.) to help your company appear much larger than you actually are.Also, no need to download anything (a la MS Office), they continuously push updates & feature improvements without need to update, includes Google Voice, Chat, Sites, Labs, etc.
