Not as great as I hoped

I'm not completely writing off the system that was unveiled today at Spadina station, but why it seems a little odd that they only put "Spadina S" as the destination. Duh. They all go "Spadina S", unless there's a detour or something. It would be more beneficial if they put "King St.", "Spadina & Queens Quay" or "Union Station". I appreciate knowing how long I have to wait for the next streetcar to arrive, but what go is it if I have no idea if I'll be able to get on it until it arrives?
