Touch screens have a cheaper cost per command input and more easily changed. Further, you can reconfigure the controls on the screen based on use to achieve way more controls than would fit in a similar amount of space.

As pointed out in the article, this is not good human factors process when the key set of command options are fixed and unlikely to change. And that hard controls for similar functions across equipment gives better cost savings in human training time than the "soft" controls give at acquisition time.

I do think military acquisition folks can "fall in love" with "sci fi" interfaces but there has been a ton of excellent research at NASA Ames which disputes the utility of such interfaces.
