When playing lying down, your hands don’t get tired (you can’t play on a regular switch for a long time lying down), and it’s much more convenient to carry it with you than a regular switch. The battery is not impressive, it lasts for ~3.5 hours of playing big games like Zelda BOTW or The Witcher, and ~4-4.5 hours if you play games that do not load the processor. In general, I am satisfied with the console, now it is the main console for playing outside the home, or lying on the couch, and the original switch will now only be used for playing on the TV.
