Something I've been thinking about - I've been playing around with Google Maps and their new vector based MapsGL (similar to the vector maps on Android) and realize that those are resolution-independent, i.e. they can be shown crisply at any resolution. The much higher resolution on the new iPad however, will take the tile-based maps from the regular ipad and simply make them smaller. I can't imagine Google is going to redraw map tiles at 300dpi, so how do you think Apple is going to address maps whose text is suddenly 3x smaller? I'd guess pixel doubling on the map tiles or something like that... but I'd love true 300dpi maps and satellite image viewing.
