I like it so far. I'm happy there's finally a clock app for the iPad. That was long overdue. And watching my buddy in Europe use Apple maps (which I guess is the default over google maps here), I'm sold on iMaps. It may not be as powerful, but it's pretty and easy to use. Just like everything apple makes.
I hate Siri, turned her off after she couldn't map "Jones Street and 8th Street" for me in NY. She kept saying she couldn't find a business by the name. Yes, because it is an intersection in one of the best known cities on earth, SIRI. DUH.
