Ubuntu take-up in Australia

[Geoffrey Combes]

I began using Ubuntu in 2009 after using MS for Windows over 15 years. I 
found it to be excellent and it has got better since. It provides all 
the applications that I need with a few exceptions, most of those being 
related to science and amateur radio (I am an engineer and a radio 
amateur). Even so many scientific applications that I use are available 
in Linux.
I am very happy with this operating system and I wonder why so few of my 
colleagues in amateur radio and others do not use it as their standard 
operating system. I also have Linus Mint running on a separate HDD - it 
works just as well as Ubuntu. When I have had the need to repair my 
desktop PC I find that repairer is unfamiliar with Linux (the boss knows 
but his repairmen don't).
So I ask AU-Ubuntu members/users how widely is Ubuntu being used? I 
notice that this website has become very quiet.
Do not hesitate to refer me to website for more information on Ubuntu usage.
Thanks, Geoffrey Combes
