The idea behind the Kinesis Form Split Touchpad Keyboard is pretty ergonomic: put the trackpad between the two halves and minimize travel for your mouse hand. The distance between the two puts your elbows at a comfortable distance and keeps your wrist nearly in-line with your forearms. The build is excellent, with low profile mechanical switches that feel smooth and just the right amount of clacky. The trackpad is responsive, but gestures only work with Windows computers. Even dragging and dropping doesn’t work on a Mac here, so I don’t see Apple users getting much use out of the board. I also found myself wishing for the slightest rotation of the keys — though they’re a good distance apart, a slight angle would keep my wrists fully unbent. There’s no tenting or negative tilt either, both of which could help a bit more, ergonomically speaking.
