> A lot of people explained that they do development using a Macbook Air on battery. Those are an order of magnitude slower than a plugged in desktop PC.

Indeed. This was a surprise for me too on Windows laptops. I think this was a change in the industry's approach to power management that happened some years ago, because I don't remember spotting these issues with the first two laptops that I've used. But in the past few years, input processing latency has became a telltale sign that I'm running on battery, on a "maximize battery life" profile.
