Instead of adhering to the qwerty paradigm that has its roots in mechanical typewriters, why no used a different layout? Or even get away from the whole keyboard mindset?
ok, come up with a new keyboard layout and see how long it will get accepted........
I have re-created an alternative keyboard to QWERTY - it is based on the Qunikey chording input system devised originally by Doug Engelbart. I call it SiWriter. It runs on the iPad and can be downloaded from the Appstore. See siwriter.co.uk for full info. The App is frankly not selling - people are so heavily wedded to Qwerty. I'm continually developing it - when I'm not looking for or doing paid work and its utility is increasing with each update. The faster the iPad the better too !
