As someone point out in the comments, repeatedly rubbing your fingertips across a surface, often at high speeds, for long periods of time does not sound very nice for your fingertips. [Controller usage in gaming is very different than typical app pointer control usage, so the use of touchpads for laptops isn't really comparable.] The handles that "curve up ... leading to greater accuracy" also sound very uncomfortable; I'm not sure "greater accuracy" is worth long-term discomfort ... I really wonder what their testing regime is like.
