By the time it was thoroughly hacked, it was too late. Much better hardware was around. People could do most of what the vita was eventually able to do with a phone.
Besides piracy what do you expect from the switch? The PSP had an ebook reader, movie player and could play mp3s as well as other cool old games very early in it's release. It could play media and play games up to the ps1. Modding a PSP vita today is like maxing out a citron 2cv instead of buying an e scooter. When the PSP came out it was amazing. Now it's yesterday's news. I'm impressed by the hackers that did it but the vita just doesn't impress even with hombrew today for the capabilities.
The PSP had amazing battery life and felt like a better Gameboy advance at the time.
