My hacking skills aren't that high, so I can't access a lot of terminals. Besides allowing you to hack though, does the process become easier with more skill? I played with the one in the Pharmacy at Super Duper Mart, and on my last try, I only had a 50/50 chance after eliminating the words in the most efficient way possible.

I general though, it doesn't seem very useful. There just ain't that many terminals around.

Edit: I forgot about drinking water. I stood in a river for 5 minutes
