The Delta app is actually very useful - I don't categorize it as "apptrash" at all. It tells me the gate, reminds me when I'm able to check in, and even has a spot for me to record where I parked my car. :) My only beef is that not all of their gates have scanners capable of reading the boarding pass barcode off the phone, so I end up printing the passes anyway.
