Weellll, it could also be useful when the GPS can't get a good lock on the satellites, as in a tree-canyon. Why would I want to use a GPS on a trainer/roller? I know where I am and I'm not going anywhere! (I know, I know, it's when you don't have a conventional bike computer in addition to the GPS.)
