I recently wrote a post about the Keys to Working From Home, this adds to that post. In the post I talk to a number of things that helped me be successful working from home. I specifically spoke to being comfortable in your workspace. Carrying on when with that philosophy I decided to make a new investment.
My prior set up had two notebooks, one with a Windows setup and one with a Linux setup. As much fun as that was, working between the different environment environment became a bit cumbersome and my desk started to look a bit chaotic with all the keyboards and mice and the sort.
