You'd think that with the DIY freedom people would be making Kinesis Advantages and slapping touchpads in the middle. But no, somehow it's the same old flat boards for arms that grow out of the chest and fingers that extend out of the hand instead of rotating on joints; with the typewriters' staggered layout that makes no sense on electronic keyboards. Only now they're a couple centimeters higher so the wrists are even more crooked, and of course there's no wrist support.
