I haven't been disappointed with it and I have found it to be pretty accurate. I was actually impressed by the way it allowed me to multitask driving directions and voice dialing my brother. It's definitely more developed than the maps app. Hopefully Apple will be able to fix maps on the fly and it will be more useable in the future. Right now I have to get by with 3rd party applications to navigate. This was a pretty serious blunder by apple. I live in a pretty big city, Boston, so not having public transit directions built natively into the app was big misstep for Apple. They need to buy or partner up with a company that has massive amounts of transit data. I don't know who they will find though since Google has that game pretty well dominated.
