I've been using Linux for the past 6 years. I felt it as user friendly as Windows for the 1st and 2 year, even though I was adjusting to the differences from what I was used to on Windows, and from the 3rd year onwards I felt that it is MORE user friendly than Windows.
A simple example:
plug in a cellphone on Ubuntu, it picks up the cellphone, installs whatever software is needed and even configures the OS to connect via that cellphone to get on the internet
All you need to tell it is which service provider you use (Cell C, Vodacom etc)
On windows, I had to figure out the connection string depending on which service provider I had,
set up a dial up connection to dial *99# or some variant of that number,
get drivers installed for that cellphone - which I didnt always have and needed to download the drivers, if I managed to find them
and know all of this in advance, including where to go to set things up to connect.
There was extra complexity if I wanted to do this over bluetooth on Windows as well.
On Linux it Just Worked.
