Usage Patterns
I don't really agree that a significant number of people are working in the "standing up with a tablet" position. My personal observation is that the vast majority still work at a fixed desk or workstation. While management level employees may be making this change, they are a small minority of all those that use a computer at work.
Given the relative size of the "standup" group, why are so many articles written about them, and so few about the majority of workers?
