as the tittle says, would you be interested in a Switch that doesn't switch and it's always like the docked Switch because you are not interested in mobility. i would buy one, because i don't want to pay for a screen, battery and those detachable controllers if i will never use them... anyone else would prefer this (cheaper console) instead of the full hybrid that is the current Switch?
No. If I can't take it out of the house with me, I lose probably 50% (if not more) of the time I've been able to play games on it. I never would have finished Breath of the Wild in 6 months at the rate that I normally play games only at home. Portability is the Switch's biggest asset. Also, the detachable controllers "that you will never use" are the most comfortable way to play video games. Whether you give them that chance or not is totally up to you. I'll take arms relaxed at my side instead of pinned together in front of me any day of the week.
