I spent a long career in sales, much of it in leadership roles at multinational companies, before I retired. KnowWiser is what I do now — partly to keep learning, partly to meet people, and partly to pass on what I picked up along the way.

I cover consumer technology and the places where technology and money overlap: what a spec sheet actually means for you, whether a price increase is justified, when an upgrade is worth it. The approach is the same on every page — start from primary sources, work out the answer, and say plainly where a number can't be confirmed.

Where an article uses a personal story or a worked example, it's labelled as one. What I stand behind is the research and the arithmetic, and we date every page so you can see how current it is.
