Articles are my research, teardown and review type publications. The contents included on these pages are a mixture of known facts, observations I made, and my opinion on devices or topics in question.
Topics [of interest] are pure knowledge listings and articles for a specific topic like common questions, jargon-busting, plug and internal connections, notable external sites and pages, and recognised distinct keyboard types. The vast majority of these pages are purely factual with little opinion mixed in.
