Asus may be trying to dodge the bullet until they figure out how to fix it without too much damage to the product's image.  My cell phone is not a "professional" gps either but I get great service from Verizon gps with the phone on my belt while driving down the road under a steel car roof.  Also no problems with it anywhere in Manhattan - city of the tall buildings!!  Another thing,  yes, it does have an aluminum back - but looks like most of the time the Prime would be used "face" up with the aluminum back on the down side -- ????
