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
• 6-key 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.

You can get a mid-level mechanical keyboard such as Cooler Master Mechanical Keyboards that's about $80, then get a good trackball any where from $40 to $70. See Best Trackballs 2018.
