I have a few questions before I buy the Droid. 1) How good is the turn by turn navigation? 2) I heard that you can set addresses for your contacts and then go into your contacts, select them, and get directions to their house like that, like a gps (save points and get directions easily), truth? 3) If I'm getting directions, and my phone rings, can I like toss it on speaker and still have my map and directions on the screen in front of me? 4) What's my limitations in call? Can I do a lot of what I can do out of a call while in a call? I'll have more questions, these are just first to mind.
