Distractions in the Meeting Room

How many times have you sat in a boring meeting watching your clock? The time never seems to pass. Thank goodness for the advancements in technology now there are many ways to keep your self from falling asleep and being embarrassed by the boss. The concern is how do we keep our selves entertained. Are we using our technology resources for the betterment of our performance or do we use it to pass the time away with out any concern for the intention of the meeting? I strongly feel that laptops should be allowed in meetings if used with some degree of etiquette. What are your thoughts? How can you utilize the handheld devices or the laptops in meetings to create a more productive outcome?
