Re: Touchscreens have their place -- on phones.
Ever used any drawing program? Notice how important it is to position the cursor or pointer exactly when selecting, say, all the #00C1F0 color in an image?
Ever notice how, as you move your finger to select on a touchscreen, your finger hides the target and a wide area around it?
Touchscreens are inherently imprecise. If you need to control something complex, and therefore have a complex interface, don't use touchscreens.
Which is what the Navy has decided. Wisely.
