Quest vs S at the moment kinda feels like the S owners got boned but a lot of features being promo'd on the quest will eventually come to the S, likely in a more refined form. You absolutely will see finger tracking etc on S. 
Then don't forget it is more comfortable to wear for longer periods of time, has better tracking, a slightly better screen and other slight QoL improvements over the Quest. 
Even if the S stays where it is right now I don't think you've been screwed, it's the better PCVR device than the quest. 

I myself do not own an S but you shouldn't be getting too down over it.
