The great irony of laptops is that they aren't really very comfortable used in the lap. The heat and contact can quickly make you feel uncomfortably warm. Not only are you liable to overheat, excessive heat is a known computer killer. Thank goodness for the Notebook Buffer; it is a real lap-saver! The patented design facilitates airflow beneath the laptop protecting both you and your computer. The Notebook Buffer also elevates your laptop to shield against liquid spills and can even be used as a cushion in your laptop bag. Fold up or roll up and take it to go! Makes a great gift!
