Wow. Four posts in a row on privacy? I think that's a record…
But I have to be fair. The Wall Street Journal published this dissenting view on where the trend is headed. In fact, they cite a case I covered for you back in August to support their claim. To be honest, when I speak of privacy I'm usually referring to using company products to conduct company business (unless you use your personal PC for that purpose).
However, the bottom line is this; it's still a crap-shoot. If you're going to perform non-business-related duties on a company PC, you run the risk that someone is going to see it. Going forward, the question will be, what can they do with it?
