Pros and cons of the CD-i gamepads > They offered speed buttons as well and the touchpad was even able to be used by left-handed people

The CD-i gamepads are not always praised for being very well designed and responsive compared to the competition. Philips even launched the CD-i without one, but soon came up with a licensed design of the Gravis PC gamepad. This touchpad offered a few benefits: Next tot he 2-speed switch on the bottom it featured a left/right handed switch on the top. When you switch it, you can turn the touchpad upside down and use the 'd-pad' like buttons with your right hand instead of your left hand. As the design is mirrored on both axes, the ergonomics are exactly the same, which is a nice feature.

At least, it was on paper. In the end, the left-handed feature was almost never used and it took a bit off the ergonomics of the pad itself. With the release of the gamepad after the touchpad, Philips put more attention to ergonomics, thankfully. It is for a reason why the left-handed function of the touchpad was never used, according to CD-i member Arethius_RGC: "One of the most useless features of all. I am left handed, never used this feature on the Atari lynx, the Cd-i remotes nor this pad. It fell unnatural to use this way."
