If you're the type of person that has a hectic social schedule, or the type of person who runs their own business, then cell phone email can really go a long way toward heightening your productivity. Instead of having to wait until you get to a computer to check your email, you can check it on the go and make sure that you're never missing out on anything. While this may make obvious sense for the "social butterflies" out there, it's equally important for business owners. If you are contacted regarding a contract, or a customer contacts you with a question, the speed with which you respond is extremely important.
