Any tablets with offline GPS that actually work?

[ouch1976]

From every review that I've read, it seems that all tablets suffer from the same GPS problems, ie they require a wifi connection to download the map data prior to starting your trip. I know there are apps out there to get around this problem, but I would love to buy a tablet that works out of the box like a Garmin or TomTom. Any thoughts?

You can either pre-cache the area with Google Maps on your wifi network, or buy some navigation app from market, such as Sygic.
