I myself use the device primarily for emulation. From old consoles to add N64, Playstation, PSP and Dreamcast really runs a lot on the device and most of it superfluid. Furthermore, the catalog of Android games is growing steadily, even ones that are playable with the controller. Even larger Android games like GTA San Andreas run perfectly on the device. eguläre tablet functions such as surfing, videos etc. of course all also work very well.
The only drawback is, I think the display. Resolution and viewing angle can ever noticed disturbing. However, this is understandable in the price range.
On the increasingly growing market for Android handhelds this is in my opinion currently the best.
Update: In Asia the Identical device is now sold under the brand iPega named iPega PG9701. Because it's really the same but cheaper by 100% through a lot, I would to grab rates for this alternative.
