You won't catch Gemei knocking off Apple products, unlike many Chinese MP4/PMP manufacturers. The United States X900 boasts a rather large 4.3 inch 480 × 272-pixel TFT screen and plays AVI, MPEG4, MP3, WMA, FLAC. The most meaningful feature, however, is the attachable game pad that looks lusciously ergonomic complete with a couple of joysticks that is operable by thumb.
It uses an ADI chip, which should be good enough for enhanced video playing experience as well as NES, SFC, the MD gaming. You can add on GPS and totally use it for directions - that is, if you're kids are not busy playing games in the backseat. Takes SD cards of up to 4GB. Also features an e-Book reader and FM tuner.
