Mechanical keys is nice. [see Keyboard Key Switch Mechanisms]
Size is good. The whole thing is no bigger than a traditional keyboard, and you still have arrow keys and number pad.
Several amazon reviewers complaint that Scrolling the trackball up/down moves the cursor very slowly, compared to left/right. This is a major problem.
The trackball has a scroll wheel, but is too small, and not as easy to use.
The function keys row F1 to F12 does not have gaps between them. It's harder to hit the right key by touch.
The thing is also very expensive. For the same price, you can get a nice mechanical keyboard, then get a nice trackball.
