Is the ipad 2 still worth it?

A friend is offering me an 32gb ipad 2 (with cover) for $300. That seems like a crazy-good deal on the surface, but I'm leery of getting stuck with a tablet that's already obsolete. I think I want to go apple, although the nexus 7 is really enticing, but I'm not sure whether or not the ipad 2 is still a good idea. Help?
