iPad owners seeking a powerful map solution have been a bit deprived lately because so far, Google Maps for iOS is native only for the iPhone and iPod touch. There is no Google Maps app for the iPad at native resolution.
WildPalm Ltd. has taken the Google data and packaged it in a Retina display-supported app called Maps Pro - Google Maps Edition that has the features of Google Maps, and they have extended it to add some features not native to the Google version.
The app, which is on sale for $1.99 for a short time, allows you to annotate maps by drawing directly on them, and you can add comments and ratings to your book
