The second sentence gave it away, Rol labeling the PSP a decent success.

It was, though. Didn't it outsell the GBA at the end of the day?

Actually for SONY perspective and their first attempt they did remarkably, and compared to Vita is like earth and heaven. and then you also have to considered how big GB market was before PSP came.
