Linux is absolutely worth it, given the assumption that your time has no value.
That has been said for years and it is as silly now as it was in the beginning.
Quite. Actually, I grow very tired of people simply placing a monetary value on everything. Life isn't about money..
It is not even that, since I spend very, very little time maintaining my systems. Maybe an hour a week, if that, this is with bleeding edge Arch installs too. I find installing things in Windows to be needlessly time consuming, since I just sit and click next a dozen times and try to remember to uncheck the crapware they try to bundle with it. Which is quicker and takes less user intervention, installing MS Office on 7 or me typing 'sudo pacman -S libreoffice'? Last time I installed MS Office for someone took well over an hour, then it wanted to update, I can install LibeOffice on my Arch system in 15 minutes, which includes downloading the latest version.
Get past the initial learning and actually using Linux is quite easy and it is simple to maintain.
