The SONY PSP E1000 so to say is a Cheap and Economic model from the PSP series, launched by Sony. This model does not have a Wi-Fi connectivity and at the same time it has just one speaker on the left side, visible in the above screen-shot. This model also has the same screen as that of the PSP 3000 so brightness and clarity will not be a problem.
This model seems to have a horrendous built quality and it actually feels as if the device parts are going to fall apart. Many people seemed to be confused about what to conclude after taking a look at this device because it has a total carbon like body which is completely diametrical when compared to the shiny gloss body that the PSP 3000 series has.
