After years of wanting to, I have finally converted all of my home computing environments to Linux (Ubuntu 16.04 LTS). This includes one fairly new desktop machine, one old desktop, and one “middle-aged” laptop. It actually was not that hard to do. Networks work, printers and scanners work, and I have found open source software to do everything that I need to do (other than taxes, which are handled via the web).
So, I am not a spokesperson for Canonical, but I do find it liberating to be shed of Windows. It is also clear that the hardware is more efficiently used and performs much better.
I use the machines for . . . basic office documents, financial tracking and planning, email, genealogy, printing/scanning, music, photos, exploring other Linux distributions using virtualization, etc. Nothing complicated. This encourages me that this type of home computing solution could work for others. In many cases it would likely simplify their lives.
For others wanting to try this as well, there are a number of references that might help. – the main Ubuntu website, the international communities that have formed around Ubuntu and other Linux distributions, webcasts such as you can find at Jupiter Broadcasting and twit.tv, companies like System76 that provide hardware (and contribute software), etc.
I really do believe that Linux has matured to the point of being viable for home computing use. Thanks to all those people that have worked and do work in an open source community to make this all possible.
