FAEbGBD,
I'm certainly not qualifed to say for sure...but it seems like when you get to the complex deep editing it would not matter to the seeing impaired if it is touch screen or lots of button pushes?

So, I hope ALL Mfgs do keep the seeing impaired in mind and provide an easy button oriented interface. Whether they do the programmig stuff using a touch screen or buttons may not matter?

It seems it would be nice for the deep editing stuff to pull the data to a PC where you could use tools that help the seeing impaired to do editing...then push the changes out? I know some of this is being done already.
Also, maybe some day a phone jack for earphone (earbud)for audio feedback of button pushes and even screen navigation?

What do you think?
