As for the PSP, it sold more units than the Game Boy Advance, so arguing that it wasn't successful when it was Sony's first fully fledged portable is crazy talk.
No one said PSP wasn't successful. Selling 80 million units of anything is a massive success by any measure, but that doesn't change the fact that DS sold twice that, which really is amazing if you think about the developers Sony has signed and games they got for their portable system.
Right now we have 40+ million 3DS units on the market, which is still a great result, when you think about how much of that market belongs to smartphones these days. Still, when Square Enix was asked about bringing Dragon Quest VII 3DS to the West, the answer was, in short "we don't know if it would be profitable". Things like that really make you think about the current state of affairs. Things like that also make you realize how way off base with their guesswork those video-making youtubers really are.
