Keyboard with Trackball
This is a mechanical keyboard, with back-lighting, and, with a trackball, and scroll wheel!
- Heavy Duty Mechanical Key switch
- Built-in Optical Trackball Mouse and Scroll Wheel with Adjustable DPI
- Blue LED Illumination with 4 Level of brightness control
- Plug and Play
- 6key Rollover
Quite amazing is that, this trackball also has a builtin scroll-wheel.
Also, they designed it so that the whole thing is no bigger than a traditional keyboard, and you still have all the keys.
Seems sometimes it's marketed as iOne.
currently, it's priced at $150 on amazon.
