The technical differences to the product E 1000, I do not know. The screen quality and feel is good. The only difference to the established devices such as E-3004 is the mono sound, what the game play but does not detract. Only those who will also play DVD movies or merchandise; There are so collectibles like Depeche Mode Devotional on UMD; is better off with the older stereo console.
The E-1004 was delivered on time from Amazon; if there's something to arrive early, it is therefore at best example of the DHL. The price difference for early customer has already targeted as a refund via mail; So the early customer get the current official rate of 95, -.
So far as I know, the price for the 3004 is available as a bundle with two games from a particular series at 129, -. However, most games are not that expensive, so that the 34 themselves - can save for stereo sound.
Moreover, the almost identical games for the PSP cost in comparison to the Nintendo DS only about half, and that's more pocket money do justice !!
