My wife loves her Ipad with 3g so much that if it broke this afternoon she would have another one before the sun goes down. She doesn't leave home without it, but for navigation I prefer and would buy a mid priced (less than $200) GPS unit over the GPS programs available for the Ipad. Don't get me wrong, the GPS on the IPad is very usefull but would be very awkward to use as a driving GPS unit.
