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...
There are a couple of things I use a windows version of that I haven’t gotten the feel of the open source equivalent.
Most of that comes from intermittent use and not using enough to transition to completely.
I recently bought a very nice Dell laptop that was a refurbished gaming system with a warranty that will take the place of the tower PCs to host a few distros in Virtual Box. eBay has a deal once in a while. The laptop looks and feels almost like a new one.
Since I have a Udemy subscription and some Linux stuff on a list, I should be doing more hands on while on the couch or recliner.
I have enough watch later of Linux training in YouTube to follow up.
