Simply put Microsoft is the worst company at naming stuff. Even when they come up with a good name for something, they'll name 3 other totally different products the same thing to maximize confusion.
I gotta say though, I'm actually not sure which VMware (well Broadcom I suppose) products I use anymore. I'm pretty sure they took the Aria name off something else they called Aria for a little while. So Aria is no longer Aria but they still have Aria but it's what used to be called XYZ
Xbox Series with X > S (so if you want the high end of the current generation you want the Xbox Series X; if you want mid-range things are more complicated because you can now get an Xbox One X, but not the Xbox One, used for much less than you'd get an Xbox Series S for and which one is "better" is a dice roll depending on the games you want to play and if 4K matters to you…)
Series is a real weird word to use there. But it also doesn't help that the versions are extra complicated because with "PC-like compatibility" in everything after the Xbox One playing just about the entire same library you need a bit of a matrix to figure out which is best for you if you don't care about the "latest and greatest".
Oh wow yes, completely forgot about that one. To me, it's a complete blur made from single words and letters, one series x s one box 360? Maybe they should create a 365, with MS office pre-installed. Or something.
