The screen has a plastic coating, thus protecting it with a film or glass is essential if you don't want to deal with screen wear after a few months of use. A bumper and a cover, in my opinion, are also essential. However, official examples are hard to come by. Items like mine require a separate purchase or an order from a reputable Chinese online retailer (whose name begins with A:). Game saves can now be transferred from the console's memory to a flash drive, and vice versa, as the system nears completion. They were previously preloaded onto a USB flash drive, and once that was filled, they were transferred to the internal storage. Because this is so obviously different from the big version, I didn't include things like the lack of vibration, the inability to connect to a TV, the absence of a light sensor, the inability to remove the joycons, or the softer button presses. Don't get the Lite version if you absolutely need them. In addition, I'd like to stress that you shouldn't rely on this gaming system exclusively. It's a movable accessory, nothing more. A computer or an Xbox/PS console will always be the go-to device. Now that Project Diva is finally being released on May 15th, I spend several hours a day playing Animal Crossing, so if anyone has any questions, I should be able to answer them.
