This is the real price of apps, everyone is so spoiled with the cheap thrills and "wow $10, Im waiting till its only $1." Welcome to the real world. If you dont want to buy this and save hundreds, go out and buy a $300 GPS. What did you guys expect a $5 app?
I don't know if anyone else has tried this one, but I have it and it works remarkably well. I've not had it steer me in the wrong direction once. http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=293287313&mt=8
I was going to be more than willing to pay $100 for this - but $200 for an app is a bit out of my reach - I can buy an actual TomTom device for right around $120. It's not like they have to manufacture, package and ship a physical item (aside from the mount)
