With all the talk about student debt, low salaries, missing employment, unwanted bivocationality and plain-old poverty in the ministry, it makes some sense to address ways of saving money as a way of making-do, because structural change (and success is not guaranteed) takes time.
That's a good reason to put free-of-charge Ubuntu Linux on an old "obsolete" computer, to give it modern utility.
With concerns about online privacy invasion, copyright overreach and vendor lock-in, it makes sense to use an operating system that is backed by a community that takes your concerns seriously.
That's a good reason to use free-to-use Ubuntu Linux, which has a community that takes these concerns seriously.
With brand-consciousness trumping utility, and the work of the ministry still being an under-served market, it makes sense to seek out an operating system that is easy (or easier) to build upon and responsive to active, if unprofitable, groups that create tools for their own use.
That's a good reason to use free-to-adapt Ubuntu Linux, which has deep communities that address very specific needs, including those of congregations and ministers.
But Ubuntu, like all Linux versions, have a reputation -- no longer fair -- of being difficult or esoteric to install, maintain or use.
If you used a Linux version before, I recommend you try one again, as a group of more user-friendly versions have developed and improved in recent years.
And that's a good reason for me to start a weekly feature -- each Thursday -- demonstrating a feature or tool on the current long-term support version of Ubuntu Linux, probably the best used and most generally useful member of the desktop/laptop Linux family.
