I tried Trello when it launched, I kind of stopped using it midway through last semester but I'll probably pick it up again for this coming semester. I've never been a Planner kind of guy so I'm not really the target market anyway, but it is a decent minimalist interface that makes the grunt work that is planning less annoying. I haven't tried collaborating with other people using it yet.
My main UX complaint is the fact that to do any real planning stuff that makes it better than a text file requires opening up the Menu of Everything for an item after creation time. There's a lot of whitespace next to the "Add" and "X" buttons when creating a new item, something as simple as offering a shortlist of the most commonly used labels or something would be nice.
