I think I could actually type faster using the predictive text, I wish Leo had it. I think it will mean less typing mistakes.
Well, this may work for people who touch type, but as for the rest of us, who have to glance at the keys much of the time to make sure we hit the right ones, predictive text might actually slow us down since we would need to glance back at the display to see when/if the OS has come up with the right word out of the first few letters we have just typed. The only way out of this conundrum, as I see it, is for the OS to actually speak the predicted word. We would then be able to accept the suggestion without looking up at the display by, for example, hitting the space bar.
