This is tempting.

I fairly frequently leave my phone in the office and take a clipboard full of lined paper and a ballpoint to a place where I can write without access to the internet - I've got a number of published CS papers and at least one funded grant where a significant amount of writing was done in longhand on paper.

Of course this would require a bit of software work and maybe a brain swap to make it into the sort of portable typewriter that I'm really looking for, but given this as a starting point it should be fairly easy.

One question I have - what is the finished weight?
