As of yesterday, Opportunity is once again a rover:

After weeks of spinning its wheels in a Martian sand dune, NASA’s rover Opportunity has finally extricated itself. Its wheels are now running freely across the surface, with no slipping.

Just in time, unfortunately, for dust storm season, which cuts into the sunlight the rover's solar panels can collect for operational power. Still, I'd rather have a slow rover than a fast, rrm... stucker?
