I've found that I get more done the less time I'm at the computer. My productivity also went up dramatically when I reduced from three monitors to one.

I solve most of my problems when I'm doing things like chopping vegetables or mowing the lawn. Sitting in the presence of shiny technology does not magically confer one with the ability to achieve higher quality decisions more quickly. I find the opposite to be mostly true. I can massively outperform the development team that my clients have simply because I am not a full time employee and can idle out long enough to think about their problems the slow way. The urgency to keep the status circle green in Teams (and related productivity theater) creates a lot of stupid decisions in many shops.
