The indicia are properly oriented with respect to the user in the first and second positions to display a telephone keypad and an alternate keyboard. The arrangement provides greater ergonomic comfort to a user when entering text. The mobile device can assign functions to each key based on a determined keyboard position and can include a weighted end piece to protect the rotatable keyboard from potential damage due to impact.
