IIRC that Delta is basically a portable RAS.  Nice get Hairy😎 
I never thought of it like that, but, I'd say you're kinda right.

Through cuts only, no dado blades. No rip cuts. But I'm 1 who says rip cuts are wrong for RAS. 

Also different from a compound miter saw, but all 3 share some uses. 
 
I made money with my tools since I was 18. I retired 14 years ago, it's just for fun now.
