I use debian 8.
If you install debian xfce, it is somewhat different from windows and it supports my old laptop out of the box.
And it's a lot easier to script than windows is. I've just written a bash code today to backup my windows dedi that runs seo crap(check out cygwin).
The thing about IM tools is that they have to be made on Windows for your non-technical users to be able to use it.
Don't be afraid to put linux debian on your desktop. It's a lot faster than windows 7.
Yes, some games run shit under wine or may not run at all, but most run. And you should be working, not playing anyway.
You simply can't beat bash scripts and crontab for backing up your everyday work, like your home directory, passwords and other project notes.
I've made the change to debian a few months ago and I couldn't be more happier.
Fuck microsoft and that you have to agree to tens of pages of licence and privacy agreements for turning your pc on, doing anything on your pc and watching porn.
