You can't put it down. It's addictive. It has to be near you at all times. If you don't have it, you feel lost and god forbid you temporarily lost it. Your world is instantly turned upside down because you feel like you can't survive without it.

Those who own one know what I'm talking about - a cell phone with email capabilities.

Whether it's a Treo, Blackberry (sometimes nicknamed "CrackBerry" for it's addictive qualities) or some other device, more and more people stay connected with email via their cell phone. Email on the go is one of technology's greatest gifts, but it can be a tremendous curse if not used with discretion.

If you are a "user", please be careful not to use your email phone at inappropriate times. This is even become a social issue among the closest of friends. Checking your email while in the company of others will send the impression that you are uninterested in their company which is rarely true, but often interpreted that way.

Also, it should go without saying that checking your email whilst trying to operate an automobile is just a very bad idea. Did you know that the runaway number one cause of car accidents is drive inattention? Yet nearly everyone who owns a BlackBerry has committed this foul at one time or another and some are guilty almost every time they get behind the wheel.

Like many other thins in life, cellular email is meant to be enjoyed responsibly!
