I have been reading the threads like the ones below, and as a casual user of 5 year experience with computers, I really am afraid for my beloved Xubuntu.
So, I am going to hedge my bets and install different distros with Xfce DE's, to become familiar with them, before things start changing/breaking (if they do).
There have been many other related subjective articles/blogs/threads I have read, too. Those are only examples.
I'm not reading them anymore, though doing so has been enlightening. I am going to use my limited time with my computer learning other things. I don't like worrying.
We'll see what washes out in the wash.
Two new drives.
SSD = for booting and installing different distros, root installs.
Larger Platter = for data partition to symlink with the root/mnt/ installs.
'tis going to be fun!
