A messaging device comprising: a keyboard integral to the message device and having plurality of keys representing the letters of the alphabet board integral to the messaging device, each of said plurality of keys having a shape that allows for angular orientation of the key and the plurality of keys comprising a left side set of keys positioned left of a keyboard center and a right side set of keys positioned right of the keyboard center; indicia is positioned on each of keys, wherein the indicia is oriented normal to a longitudinal axis of the device and each of the plurality of keys are oriented at an angle relative to a longitudinal axis of the device; and a display operatively coupled to the keyboard wherein at least one key of the plurality of keys of the keyboard is oriented at an angle that optimizes use substantially with thumbs pursuant to user thumb typing. 5. A handheld electronic communication device, comprising: a device housing having a left edge and a right edge; a display; and a keyboard having twenty-six letter keys and at least one other key, the letter keys being arranged in an upper row including 10 letter keys, a middle row including 9 letter keys and a lower row including 7 letter keys, the letter keys in the upper row being distributed from adjacent the left edge to adjacent the right edge; each letter key in the lower row being in substantial vertical alignment with a letter key in the middle row, each letter key in the middle row being in substantial vertical alignment with a letter key in the upper row, the keys in each of the rows being disposed on the opposite sides of a vertical reference line substantially midway between the left edge and the right edge, the keys in each of the upper and middle rows disposed such that half of the keys in each of the middle and upper rows are on each side of the vertical reference line, five letter keys in the upper row being disposed on each side of the vertical line, five letter keys in the middle row being disposed on one side of the vertical reference line and four letter keys in the middle row being disposed on the other side of the vertical reference line, and the keys in the lower row being disposed such that four letter keys are disposed on the one side of the vertical reference line and three letter keys in the lower row are disposed on the other side of the vertical reference line. 6. The device of claim 5 wherein at least two of the rows have the same total number of keys, and the keys in each of said two rows are distributed from adjacent the left edge across the top surface to adjacent the right edge. 7. The device of claim 5 wherein in each of the upper, middle and lower rows each letter key on the other side of the vertical reference line is symmetrical relative to a respective letter key on the one side of the vertical line. 8. The device of any one of claims 5, 6 and 7 in which the upper row and the middle row have the same total number of keys. 9. The handheld device of claim 5 wherein the housing has a top surface and the display and keyboard are positioned on the top surface. 10. The handheld device of any one of claims 5, 6 and 7 in which each of the letter keys is oblong. 11. The handheld device of any one of claims 5, 6 and 7 in which each of the letter keys has a height greater than its width. 12. The handheld device of claim 5 wherein, in each of the upper, middle and lower rows, the centers of all the keys in the row other than the keys most closely adjacent the left edge and the key most adjacent the right edge are displaced from, and lie on the same side, of a straight line extending from the center of the key of the row most closely adjacent to the left edge to the center of the key most closely adjacent the right edge. 13. The handheld device of any of claims 5, 6 and 7 wherein the keys in the middle row are arranged across the width of the device from adjacent the left edge to adjacent the right edge, and wherein in the middle row four letter keys and an at least one other key are positioned on the other side of the vertical reference line. 14. The handheld device of claim 5 including an auxiliary input device, and wherein a displacement of the auxiliary input device in one direction provides a selecting signal and a displacement in a different direction provides an executing signal. 15.
