Sure, they're neat and all. But really, how practical are they? Think about how you use your iPhone when you're in your car. I tend to talk on mine from time to time. And yes, I will read the occasional text. Oh yeah, and I listen to music and podcasts which requires picking it up and scrolling through menus and whatnot. Am I really going to want to do any of this if my phone is docked on the windshield and running TomTom or Serius/XM? I'm sure plenty of people will buy them, but I imagine they'll regret it later down the road.
