@Indigo @Tadano Honestly, I didn't think anything of the two screens. I was more blown away by the polygonal 3D graphics running on a handheld. Honestly, it was the only system that blew me away in terms of power. I wasn't even born yet when the leap to 3D happened on home consoles.
I was also shocked that Nintendo released a new handheld that wasn't a GameBoy. I thought that every console they will release will have the GameBoy brand.
The concept of two screen wasn't anything new. Some Game&Watch models had two screens and it's where the design of the DS came from. You also had the Dreamcast with the VMU and the GameCube with the GBA-Link Cable. A few arcade games also utilized two screens. Granted, I didn't own or played any of those, but for whatever reason, the whole two screens concept didn't wow me. I guess I was used to seeing fictional game consoles on TV where the controllers had screens.
The concept of a thing with two screens was just too much for my brain to process at the time.
