Above the privacy concerns that MS captures your data that they can have their hands on quick and loose and the way they please their terrible record of ruining long living basic functions is a second reson not to go for laptops with Windows, not trusting it for reliabile functionality and handling any private data of mine. Having a completely isolated separate computer for company data on Windows that belongs to the company - they seem to feel easy about handing over all confidential data to them to store and manage, so I do not need to worry there.
