I do this too, and I run my mindmap software on it too. About a year ago, I used a netbook with Ubuntu 13 on it as my daily driver. I felt justified in having used Perl and stable/traditional HTML/JS for most of my code, because I could run it almost without any modifications on that laptop, and it helped me track down performance bottlenecks. I think there are many huge benefits into putting thought we put into backwards compatibility, including being able to reuse older hardware instead of throwing it away, which itself has many resulting benefits, not least of which being lesser environmental impact, but also the pleasure of using a well-made device while it is still working. Another great benefit is the Lindy Effect. The more backwards-compatible you build your software, the more forwards-compatible and resilient it is likely to be in the future. I personally prefer software which I do not have to maintain as much, and I like offering a repo which doesn't require a lot of fiddling with package managers and dependencies in order to get running.
