I suspect the D-Pad was added largely to mirror the 3DS' profile - again, 3DS fans being the Switch Lite's primary market - but I like to think it was partly because someone at Nintendo saw all those posts about players modding D-Pads onto their Joy-Cons. We'll see how well it's received soon enough, but for now, head down to the comments section and tell us what you think of the Switch Lite!
As it is a dedicated handheld console, it can not be docked to a bigger display.
As for the disadvantages, HD rumble and IR motion camera are not part of the Switch Lite.
The pint-sized console sports a 5.5in 720p touch display compared to 6.2in for its predecessor, and comes with its Joy-Con controllers built right in. Yes, but you will probably need an additional Joy-Con controller or controllers to wirelessly connect to the Nintendo Switch Lite in order to play party games. The Switch Lite measures 91.1mm x 208mm x 13.9mm and weighs 275g while the Nintendo Switch measures 102mm x 239mm x 13.9mm and weights 297g. It plays all the same games, but it's not a replacement for the OG Switch. On the rare instances you come across a game in the eShop that requires Joy-Cons, you'll get a warning before purchasing on the Switch Lite. Nintendo says that it will clearly mark games in retail packaging and online.
