Can anyone compare this to the Google Maps on Android? Downloading vector based map will obviously use less data than raster map image (different one at different zoom level nonetheless). I don't see how this is much of a news.
It's news to anyone with an iPhone that has to pay for their data when downloading maps @ $0.15/megabyte when traveling internationally. I've racked up $20-$30 just using the maps application on a single trip, so this is positive news for me.
