I'm halfway between a technical and non-technical user. And half my time is spent in Chrome. But my other half time is in Excel, Dropbox, and Everything. Do those run on Linux? Maybe there are equivalents but I don't have the time to investigate. Access crashes too frequently these days but I couldn't find a GUI equivalent for PostgreSQL. Spying/ads/breaking the misc aren't in my top 10 Windows issues.
