What is this capacitive screen?

The width is enough but as a capacitive screen (does not need a stylus) has a touch sensitivity of around 5-7mm the keys are too close together to be workable.

This is why the touch design that was discussed was perfect as the keys were larger and the distances between keys greater.

The new screens are much improved as they allow for us to get rid of the stylus, support multi-touch, etc.
