Sony has released videos for both the Digital Reader and PSP minis.
We have both posted after the break courtesy of Joystiq.
For now, the Digital Reader is for comics only, but who knows what the future holds. Digital copies of Wuthering Heights, The Doppelganger or Atonement may not be just a pipe dream folks. We'll have to wait and see.
Minis are expected to launch with the Go on October 1. Yay.
