one time I did a test. I had two computers the exact same model - both were low end cheap walmart emachines. One I installed linux mint and the other I installed windows 7 from a full version retail disk. I also installed libre office, gimp, vlc, firefox and chrome. For security, linux did not need any, windows needed an antivirus and antimalware. To get everything installed and updated in the linux mint computer, it took almost two hours, to get everything installed and updated in the windows computer, it took over 12 hours mostly downloading, installing updates and drivers with all the reboots in between.
If you have a linux computer, you can pull the drive and move it to just about any computer and run it, you cannot with windows - with windows, it will only work if the computers are similar but then there is a good chance it would be declared non-genuine for a license violation.
linux can be ran from a cd, windows cannot.
I just want to be able to do what I need to do on my computers without nothing fancy, without worrying about security, without the need to purchase updated programs because of some update. at this time it looks like linux fits the bill.
