I'm not sure about companies collecting location data / travel profiles through a N810. If this business model would work, they'd have done it long ago with cell phones: You can track the position of a cell phone well enough to create such a profile for your customer. Also, a device like the N810 would very likely soon feature software to spoof/block GPS data.

Apart from this one point, it all makes perfect sense. I dont expect the Italian tour to happen in 2008, but it's not too far away.
