The minimini is a tiny mobile phone with integrated MP3 player and color OLED screen sold in Taiwan.

The GPLUS ES813 (minimini) measures 90.6x33x19.2mm. Compare this to the premini-II (105mm×46mm×19.4mm) or the Minimoto (90×32.4×21.2mm).
The GPLUS ES813 is a bit smaller than the minimoto available in Korea. It has the looks of a typical MP3 player, but features a 0.3MP camera and a GSM phone. Music can be stored on a Transflash card. Making mobile phones really small is a great development. Larger phones are only relevant in the future for online web access or watching TV.
