I just sold mine recently.
Steamdeck makes it obsolete.
Also, the psp controls were not very good. The stick is tiring to use, the movement buttons are a bit far apart. I did like the mp3 player when traveling and the movie on a umd gimic was interesting.
I did like it overall at the time, but being able to choose to be not bothered with online services (as the article suggests) is just as viable with a steam deck. Except when I DO want to use an online service such as my plex or jellyfin, I can do that too. Movies on a plane streaming from home, amazing.
