No, because I'm pretty sure iMaps will be more simplistic to use.
How so?
Voice actions: "Navigate to Westminster, London" Or "Navigate to postcode"
Contacts: Tap on contact, tap their their saved address and open in Google Maps.
Latitude: Tap on friends avatar in Maps, get directions,
SMS: Share your current location via SMS from maps, friend has your exact location and navigates to you.
Then there is good old simple name search. Search for McDonalds in browser, tap on Google maps link in browser which can open Google Maps and navigate to McDonalds
I can't think of many more integrated simple ways of navigation myself.
