Perhaps it’s surprising to see gmail as a resource, but for those who are not already using it, it’s an amazingly useful tool for organizing your life and business. Not only is it easy to use, organize and search, it effortlessly syncs on your smartphone, iPad as well as on the web. You can keep track of your tasks, schedule your calendar, access your google documents (shared or private) and use gchat (and IM client) as well as google call (VOIP), all right from gmail. And you can set it up to send from and receive using your professional email address as well. Text, voice, video chat and email…could you want much more? Plus it’s free for individuals. There’s an enterprise version as well.
