EDIT: Here is a gimped photo, with placement ideas for multiple arcade buttons. I wouldn't put so many of course, but up to 4 total is reasonable, and it's way easier than adding cherry switches. Thoughts? Ideas?

First thought? Looks like a spider with eyes all over its head
Too lazy to web search a good pic though
Even though I have not done this mod myself, I believe the palm actuated arcade buttons are a major ergo game changer. The finger/thumb arcade buttons can be great for non-oft used/farther away buttons, which is also great for an easy target to hit, but I think the couple palm buttons for oft-used buttons (ex: SHIFT) are huge. Taking away pinky work and not wasting the precious thumb keys. Excellent. This is almost exclusively a Kinesis only "feature" due to the unique case design.
MODS THAT PROVIDE MAJOR IMPROVEMENTS TO THE KINESIS DESIGN:
1-Integrated pointing device (by far the single largest ergo improvement, HANDS DOWN!!!)
2-Split into two halves (increases comfort)
3-Palm arcade buttons (major ergo feature for oft-used buttons)
4-F-keys as mechanical switches (allows for real touchtyping and increases convenience)
5-All other mods add a fraction of what the above mentioned items do to the overall functionality and design of the Kinesis keyboard. (My opinion)
