Kept getting exploited to hack consoles because Sony sucks at using hypervisors (although I'm anti-DRM, so...).
XBone and Xbox Series still haven't been hacked, outside of a barely used escillation bug in devmode since MS uses hypervisors for everything, which essentially sandboxes everything into their own VMs.
Porn was by far the best thing I ended up using my PSP for. It wasn't advertised for that purpose (luckily), but I'm sure a large portion of younger owners found out that was the true purpose of the device.
