After using multiple Blackberry devices (8700, Curve, Flip, Pearl, 8800, 7130) I have come to the conclusion that the Track Wheel, while not as cutting edge, is vastly superior to the trackball. Why? Here is why, see if you agree.
Although I am right handed, I can easily use the Track Wheel, while holding my Blackberry in my left palm, and using one of Three fingers (index, middle, and ring) on my Left hand to manipulate the track wheel and back button. This leaves my thumbs to be used mostly for typing on the keypad, I can also use the Blackberry right handed in its conventional one handed style, with my right thumb when I am unable to use both hands, which is seldom. This virtually eliminates the chance of Repetitive Strain Injury, otherwise known a Blackberry thumb, by spreading the load, so to speak among more than just the thumbs.
The Track Ball, can be only accurately used with either one of the thumbs, using any other fingers usually results in the curser being lost on the screen, unlike the Track Wheel that uses orderly top to bottom movement of the curser and positive clicks.
So, what this means to me is, to stock up on Track Wheel Blackberry’s for the near future. What this means to others, well, maybe nothing, until that stabbing pain starts showing up in their thumbs.
So what do you think?
