Would you mind sharing how you improved the keyboard?

Read this amazing thread:

(It gets better towards the end..)

I actually ordered one of those a couple of hours ago :)

I tried ordering one before but the 3D printer operator said the design was unprintable.

Does it make the device easier to use? Is it comfortable to type and play on now?

Its very much a more usable device with keys now .. I honestly think that NextThing should get behind this community effort and just start making PocketCHIP's with cases based on these designs. Its a very different instrument ...

Anyway, good luck! :)
