Sure, if you do not see value in spending time learning about computer internals (through fixing issues that pop up) then it is not time spent well.

During the last few years using my 2008 MacBook Pro I find it harder and harder to get stuff done. As a software developer I have to install/upgrade/configure certain software TOOLS for my work that I can not in a flexible robust way using MacOS X. That is the main reason for me to ditch the old fruit, apart from the proprietary mess that is Apple/Microsoft.

If it was "learning about computer internals" that would be one thing. Most of it is closer to "learning which kernel version randomly works with your hardware" and then rewriting your tiling window manager configuration file because the old format isn't supported anymore. You could spend that time studying an EE textbook instead and get more widely applicable knowledge.

Whatever makes you happy is fine, but beware putting yourself on a high horse with statements like "if you don't see value in learning...".
