Gizmodo is reporting this morning that the new car kit/ dock for the iphone/touch is going to cost $120. Add this to the $100 they are charging for the app, and that makes it a whopping $220 to use the touch as a GPS device. And only in the car, since it needs to be plugged in to operate. I did a quick search on Amazon and found that most standalone GPS devices range in price from $100- $200. So I'm curious- does anyone think that the kit + app is worth the price? What's the advantage? If you're in the market for a GPS would you get this, or a standalone unit?
