Negative Positive
Title: for those with ordinary thumbs
Review: Trackball users can choose between thumb- and finger-operated balls. For those who can remember when the "mice" first appeared, "finger-" is better. The predecessors for this Logitech Trackman were superb and lasted a dozen years or more; one finally succumbed to being dropped once too often. The new one is sleeker but otherwise the same. I expect at least a dozen years of enjoyable use.
Is the review positive or negative?
