Miles Electric is a portable computer used by Tails in Sonic Unleashed and Sonic Colours. The machine can be connected to the Tornado-1 to use as a control interface, and it also allows Tails to talk via videophone to Professor Pickle and show Sonic any interesting tidbits of information.
The device is usually shown on the Xbox 360/PlayStation 3 Unleashed loading screens, often displaying handy controller hints on how to perform Sonic's various special moves. In Sonic Colours, Tails uses it to translate the language of the Wisps.
