I never felt comfortably in my small business with employees having internet access. Similar to the way they'll take car of the company's car vs their own. On the internet a few would tend to go where no man has gone before. One upside to smart phones is they'll tend to hide their surfing habits via their phone and I noticed a definite reduction in viruses as the smart phone evolved.
