It's easy to transpose, yes. MSP helps to remember the key(s). I have a collection for every band / line-up I play with. So it's helpful to have a song in one key in my "Frankenbaend" collection and in a different key in my "Moonlight Crisis" collection. When creating a setlist for a gig I choose the songs from these collections and the songs appear just how I need them.
