Me, I rarely, if ever use the functionality. However public facing people like my wife, an attorney, real-estate agents, financial consultants really love the functionality. Between Sprint and Verizon I had hoped they had enough pull so that the functionality was included.
If I was to make an excuse for apple, the way they designed this phone with the battery off to 1 side while the motherboard is on the other side, it seems that there's a limited amount of real estate in there and a separate radio path for EVDO was a tradeoff that they could have been limited by. Anyway,like I said, they could have sucked off some of the professionals that highly value SVDO and other GSM telephony features from AT&T. Missed opportunities.
