23 years and counting
I've used Linux in various flavours as my daily desktop since 2002, which almost qualifies me as a 'veteran'. I learned my Unix skills on SunOS 4.x during gap year work placements, and started playing with Linux in the late 90s. It was harder work back in 2002 (the same year we first got 0.5Mbps "broadband"), but still fun. Now, it's as easy as anything else, or easier, and prettier.
But all that incredible power and flexibility is right there, a click away. I could never go back now. Working in Windows feels like trying to do gymnastics in a straitjacket, although I will accept that if you really need the super advanced productivity stuff, MS Office is leagues ahead of LibreOffice. But 98% of people outside a corporate environment simply don't need that.
