As the number of little computers explodes, investigators will have need to record what the computers do or display. Recordings like this video may need to be used years later in court or in a tax audit. I explain this recording with a blog article: http://hack-igations.blogspot.com/201...
Footnote: Video cuts off before I finished saying "11:23 am". A meticulous investigator would make sure he knows how to use the technology so that a little detail does not get cut off at the end.
