good info! I think a notable mention is the hybrid - the iphone for example has a GPS antenna built in and I use Navigon on it (have Tom Tom also but Navigon is better imo) and it has done good in the place of a stand alone unit. When GPS signal is scarce it can use cell towers to help triangulate your position.
