I remember during the 90's The gameboy is a big thing, You are not a cool kid without one. In the Early 2000's it is all about the PSP and Nintendo DS. I thought the Nintendo 3ds and PSP vita will be a huge thing but I rarely see people who plays them. I don't even see any pocket console game getting hype like their predecessors do. Most people seemed to be more interested with Game apps for tablets and smartphones because most of them are free. I have a feeling that PSP Vita and Nintendo 3ds might be the last pocket game console because everything they can do can be done by a Tablet. I know the tablets and phones dont have buttons so gaming with a pocket console is much more comfortable but kids of today and even the kids at heart don't seem to be interested with pocket consoles anymore.
