I think he had some valid comparisons though.
Nintendo didnt have color until 1998 when Lynx had one in 1989.
They didnt have a backlit screen until 2003 when Game Gear had one in 1991.
They didnt have a touch screen until 2004 when Game.com had one in 1997.
They didn't have a control stick until 2011 when Tapwave Zodiac had one in 2003.
Oh yeah, I definitely agree it's nothing new for them to be behind the curve. Again, I never owned any Nintendo handheld prior to the 3DS so I do't have strong opinions on those. All I can say for sure is that my 3DS always did feel like a second rate product, especially compared to the Switch.
