You might change your mind if you ever have the opportunity to rent a car that has a HUD - having just the navigation directions on the windshield is great, your eyes never leave the road.
Rolls Royce, BMW, and even Chevrolets (Corvettes and Camaros) come with HUDs of various sophistication.
Having driven HUD cars on several 800+ mls roadtrips, i prefer BMW one the most. Camaro (2012 model) was so distracting, i had to turn it off due to glare at night.
BMW HUD is truly useful, but youre NOT TRULY looking at the road while looking at it - your eyes are focusing on a point in road that's only about 50 feet from you. Granted that's better than your lap where the cell phone is, its still not enough time to react to something happening in front at highway speeds - so as many have said, bringing texts/full voice interaction to this thing strikes me as dubious.
Also, wouldn't cops consider it to be a windshield obstruction? Its a giant box on top of the instrument cluster... many petite members of our society barely clear the steering wheel with their eyes...
PS: After about a week with a HUD you'll have a hard time going back to a car without one, but i don't ever see how this would be safe for anything except GPS.
Lastly, MSRP looks to be ~$450 - which is not far from integrated navi system (with which you get proper Bluetooth, traffic, no data plan requirements, and so on).
