Pinterest for iPhone and iPad updated with push notifications for comments, likes, and repins

Pinterest for iPhone and iPad has been updated with a few new features including the ability to send a pin to someone (iPhone only) and push notifications for comments, likes, and repins, suggestions for search. You can also invite friends to pin with you on group boards, pin from the web, and mention your friends in comments.

Any Pinterest users out there? What do you think about this update? My favorite new feature is the ability to send a pin to someone -- been wanting to do that for awhile now, though I wish it was also supported for iPad.
