(ab censors the microsoft link just google virtual pc 2007 )
linux - well it's linux - based on unix - and written by some really brilliant people - the trouble is - it's a bit like a restored car - happy memories - exciting to drive - uncomfortable as hell - only practical to take out on a sunday if it's not raining
the whole point of linux is it's an enthusiasts operating system - it takes 300 lines of code to configure a network card ..... and that's the whole point of linux - the fact that you know the 300 lines of code - and the unending fun you can have just to get your system working.
in an atempt to increase popularity they pushed a front end on it that looks remarkably like windows - which they said looked remarkably like macOS - which looked like the operating system xerox developed in the 70s (using unix!)
it's actually a good way of getting to grips with how it all works - but the whole idea of an operating system for most - is what it operates - it should be invisible
