As a student, I love mykis.
$410 for unlimited zone 1, 2, vline and regional bus all year since they can't fix the system up properly yet. Sure, I doubt I would use regional bus, but it's nice to know that I can.
Also, since I'm a student, my one doesn't work on trams and stuff still, but if a ticket inspector pulls me up, I just show my concession card and (s)he walks past
