Linux and Windows 7
A lot of scorn and down voting from people who only connect mainstream devices like printers and scanners.
Anything niche, such as a sat nav, a blood glucose monitor, bicycle computer seems to come with software and drivers for the most popular OS.
Which is still Windows.
I was a long term Linux user (and Unix before that) but I have found no need to use Linux recently and am still dragging my feet over moving to W10 from my W7 systems.
Yes, I have W10 systems and W8.1 but W7 seems to be the sweet spot for "mainly just works".
It seems that there is still a lot of religion over using Linux instead of Windows.
It still doesn't hit the spot of "does everything I need and supports every niche device I need" but Windows does.
Until all devices come with Linux support then Windows is still the default.
Saying "use a VM for Windows specific hardware" to me is complicating the issue.
If I don't need anything that only Linux provides then why complicate things?
Or fire up a Linux VM, of course. :-)
