OK, I'll admit it, I'm mostly a Windows user. I have four or five Windows 7 machines, filled with all kinds of design / authoring / instrument interface / simulation & embedded stuff / etc., software and drivers, much of it fairly old stuff that works well for me. (Windows 7 compatibility mode works well). I suspect many other engineers share my situation and preferences.
There are rumors that Windows 10 may be better / safer than Windows 7. And Microsoft is making a serious push to get us to accept the free Windows 10 upgrade. But I'm afraid of some kind of meltdown. I'm wondering how many of you have upgraded and what your experiences were.
