people who are already suspicious

see, that's the problem. it's not a technical issue. it's lack of trust. i am not saying that there are no issues, but by far the biggest issue is and has always been expectations and trust. the expectation that there will be no problems, which is not even fulfilled when you upgrade windows or word, and also the subtle differences, quirks that you got used to, are different now.

it's resistance to change, while completely missing that microsoft forces more change on their users than linux or libreoffice ever did. if we could sell a switch to linux/libreoffice as a windows upgrade, people would moan, but it would not be any worse than an actual windows upgrade.
