There are a few good articles on the distrowatch.com website, right now.
1. An article about a kernal patch that could offer a 20% power savings.
2. Reasons to try the BSD OS
3. Swapping a hard drive from one computer to another. This of course is only with the Linux OS, on the hard drive.
#3 was particularly interesting. I have done this several times with the Mac OS without a problem. I tried it once with Windows, and it didn't work. I tried it twice with Ubuntu between two Macs; once it worked and once it didn't.
Interesting. From a brief scan at the article linked about the kernel, it looks like this has been added to 4.17 if I read it correctly.
