Cellphone-only households
I'm not surprised that cellphone-only households have not grown as fast as they were first expected to grow especially as the quality of wireless connections continues to be spotty at best. There's a reason why Verizon uses the "Can you hear me now?" phrase in its ads...since they seem to also have that problem. According to this WSJ story (subscription required):
While the number of wireless-only households is increasing -- close to 6% of all U.S. homes at the end of last year, according to Forrester Research Inc. -- the trend isn't accelerating as quickly as many experts predicted. And some consumers are reconsidering their decision to go wireless and are reconnecting to a landline.
...When the Federal Communications Commission in November 2003 began allowing customers to switch their home phone number to a cellphone, a huge shift to wireless-only consumers was expected. About 820,000 people did make the move through the end of last year, according to the FCC, but that was only a fraction of what was predicted.
