But it would be unfair to write off Sony’s travails in the portable gaming industry.
The idea of a portable PlayStation was something that seemed inevitable as soon as it was clear that Sony was serious about games.
The real bombshell dropped just ahead of E3 2003, when Sony announced the PlayStation Portable, or PSP.
But with the PSP, Sony saw a broader opportunity in mainstream consumer electronics.
While Sony probably won’t ever make another portable PlayStation, the two it did make were entirely worthy of the PlayStation name.
