If you don't follow Macfilos web site you should. Michael and I became friends a couple of years ago when I was looking for advice on purchasing an 11" MBA. Michael was also one of the people I interviewed for the Running on Air series.
Michael writes on a wide range of topics including technology, watches and photography. In 2011 Michael wrote a piece called Pre-Tech Office: Office work in the historic 1960's that was really great. Microsoft recently create a page called A Brief History of your Office and interviewed him about the technology in the offices and what was common place. Michael has two short video interviews of what the office technology was in like in the 50's and the 70's. Both are really great to watch (very short), please check then out.
