I have a few hand me down Dell laptops that have different distributions of Linux and I’m getting better about using them more.
I’m trying not to be such a hypocrite in a way since I picked up a couple of lightweight LPI certificates since they were fairly easy and inexpensive and use Windows primarily.
Someday I might able to face Linux+ certification.
There are some others ahead of that.
I’m not an expert at all - just a user. We just got very pissed with MS, and didn’t want anything to do with them anymore. Changing to using LINUX was very easy for me (I have a personal ‘Beast of Burden’ to do the hard technical stuff for me :-)
I don’t find it much different from using Windows at all; but I wouldn’t know about everything under the hood...
