Of course, we have to remember we are just seeing a tiny clip.
It's possible (likely??) that the mention of the X1000 is just a little blurb at the end showing that it's still going in some way... (With a catchy kual sounding name)
Yes, they could include other options (AROS/MorphOS, etc), but if I went to the average person and said they still make an X1000 computer that runs a new AmigaOS, they will probably say something like "Wow.. Neat.."
If I tell that same person you can still get a machine and run MorphOS, they will go, "Um.. what's that?"..
It would require more explanation. If you're doing a video and looking for a quick little "it's not quite dead" bit, X1000 (kual sounding and reminiscent of Amiga 1000) and AmigaOS is much nicer.....
Now, if you're documenting the CURRENT Amiga situation as completely as possible, then you need to include the others..
But for a historical look at the Amiga, maybe not so much..
