A binary (literally black-and-white) 400 x 240 screen. In 2019. For $150. Oh, and each game will be automatically downloaded, its contents kept secret until the week of its release. At least you'll be able to side-load the old games, but why not give us the option of downloading or not downloading the new game? And why not give us color? Black and white is fine if it's a legitimately old (pre-Game Boy Color) handheld from when technology was limited, like the Game Boy or the Mega Duck. Even those gave you multiple grayscale levels though.
This thing is going to flop hard and 20 years from now is going to be just a rare curiosity.
