I have recently upgraded to Linux Mint 17 ‘Rebecca’ which is a LTR (long term release) which will get regular software updates for the next 5 years.
Although I had previously loaded ‘Qiane’, the previous Mint release, I discovered that it had stopped uploading updates and on examination,it was ‘saucy’ updates which had stopped.
It was curious because these updates were from a past expired distro.
I am so confident and pleased with Linux Mint that it now is my main and sole OS.
I no longer run a dual boot with Windows. That shows a real vote in favour for open software.
