The people who are losing sleep right about now are the carriers that didn't go with Apple.
My carrier, verizon, who I hate with a passion, will be losing my business within 90 days when my current contract expires. The Apple iPhone 3g, combined with MobileMe (the new .Mac upgrade) and a home Mac will give me the most comprehensive and consistent computing platform on the market today.
Ironically, Apple approached Verizon about the iPhone, and Verizon told them to take a hike—they didn’t want to implement Visual Voicemail.
Apple then went to AT&T and the rest is history.
