What replaced the PSP?

Could you please elaborate on the topic of what replaced the PSP? Are you referring to the PlayStation Portable, a handheld gaming console from Sony? If so, I'm curious to know what specific device or technology has emerged as a successor or alternative in the market. Alternatively, if you're discussing PSP in a different context, perhaps related to finance or cryptocurrency, I'd be interested in understanding the context and the potential replacements that have emerged. In either case, I'm looking forward to your insights.
