I find it amusing that so people who are quite capable feel compelled to hold onto the hand-rails for so long and won't just dive in to Linux. I was guilty of hanging on to the dual boot for a few years but never ended up using the Windows side or any of those programs that I thought were so fundamentally important to my life.
I am not sure why people can't just give Ubuntu a go on a brand new machine rather than maybe run it on Virtualbox. It is like cars and bicycles, people will spend all their money on a car but want or insist on some second hand stolen junk when it comes to buying a bicycle. In so doing they never get into cycling and spend even more money on their car. Then one day they hear about climate change and maybe decide to get the bike out the shed.
I feel this is the same story here, since when has there been any information privacy with these commercial operating systems? DOS 6.22 with a locked floppy drive was probably the last time. So to suddenly wake up to the 'scandal' of Facebook et al. selling your every mouse click is a bit special.
These are just observations, obviously Ubuntu linux is the best operating system there is and I would not change for a paid for OS if you paid me.
