I was doing little research on natural keyboards (it's been a while that I have bought some electronic gadget) and I came across some of these amusing facts.
This particular article from Inquirer says 'natural' keyboard is a wrong design. I didn't know that shifting to natural keyboard needs some learning (which is apparently less for touch typists).
This is another funny link that tells how to make natural keyboard from regular one.
But now I have abondoned the plan of buying a new keyboard. :)
