MorphOS is not Amiga related period.
As some one that has never used MorphOS or even seen it "in person"... I've only seen it in videos on the internet, I'd have to disagree just "a little bit" with that assesment.  Let me list the reasons.
1. Amiga- Uses a Mouse . . . MorphOS- Uses a Mouse
2. Amiga- Uses a Keyboard . . . MorphOS- Uses a Keyboard
3. Amiga- Can be viewed on a 'Monitor' . . . MorphOS- Can be viewed on a monitor
I could go on, but seriously....
Reminds me of the movie good morning vietnam.
RedTroll: "Who brought in the MorphOS?"
RedTroll(Again): "I SAID Who brought in the MorphOS?"
A.org member:"That's all right. I did. 
Hey, come on now.
If you kick out the MorphOS, the next
thing, you have to kick out the AROSes,
the DraCos, the WinUAEs and AmiKits.                   
All that's gonna be left in here
are a couple of brain-dead rednecks."
