I've been struggling all day to contain the hype, but I do think this definitely has the potential to be "the next big thing" as long as they can keep the battery life long enough and it's enjoyable to play on the go.
Yes some of you are disappointed that it's not going to run 4k games at 120fps, but Nintendo was never going to build this to go head to head with Sony/MS, they've lost that war at this point.
You are exaggerating on all counts.
