Mm. I don't know so much.....
I used to be a died-in-the-wool XP user myself, but I saw sense when EOL came around. I switched to Linux myself (firstly Ubuntu, followed by a few other 'mainstream' distros).....then an acquaintance at the Ubuntu Forums put me onto Puppy Linux. For the last 4 years I've been exclusively all-Puppy, and there's nothing I could do on XP that I can't do with Puppy.....even running all the programs I used to run in XP under WINE.
I run a 15-yr old Compaq desktop (one of the last made before HP took 'em over, and reduced the once-proud Compaq name to a mere mention in its dreary line-up.) I had to switch away from Ubuntu, since Canonical compile their own kernels.....and arbitrarily decided to 'drop' support for my old ATI graphics chip. Mark Shuttleworth, Canonical's boss, sees Ubuntu as a Win 10 competitor, so wants it to support all the very newest hardware.....and wants to move away from the traditional Linux image of keeping elderly hardware useful.
Puppy uses bog-standard kernels, so the problem doesn't arise. It flies with most older hardware, and, on this old Compaq desktop (running an Athlon64 X2 3800+ @ 2.0 GHz, w/3 GB DDR1 RAM), would give top-end hardware running Win 10 a bloody good run for its money.
It's worth a look, since it's been designed to be easy for Windows 'refugees' to get on with, and is all GUIs, tooltips, wizards for setting up everything you can imagine, etc.
I'd recommend it to anybody.
Mike.
