I would not recommend the $40 VZW D4 car mount. I bought it yesterday thinking it was the same as the $60 mount in the Motorola Store/Amazon (it's not) and returned it today. The VZW mount does not come with a power cable/charger and the 3.5mm jack needs to be plugged in every time you dock your phone to get audio from your car speakers, whereas the $60 mount has a 2-in-1 cable that connects both power and audio via USB. Definitely worth the extra 20 bucks IMHO.
Hm, I had the option to buy a few of these with the phone and I skipped them. But now I find that the phone doesn't charge with my current DC-USB adapter and I have to buy a new adapter anyway. So annoying. Even with "standardized" USB ports they're still screwing this up.
On a side note, I'm also looking for screen protectors. Any recommendations on anti-glare vs other choices?
