Is there anyone out there sold on the iPhone but still yet to buy? That's the question survey company Lightspeed Research set out to answer, and they've come back with some impressive results: they're saying one in three Americans wants an iPhone. In fact the top reason for all that frothing desire is the promise of successful convergence; having music, movies, internet and wireless all in one device.

My usual qualm with surveys like these is the size of the group questioned, but Lightspeed seem to have covered that base too. 39,000 people were quizzed in the days following the iPhone's introduction, and a further 34,000 on July 5th, leading the company to suggest with some certainty that the already-iconic handset could be the most successful launch this century.

Out of those questioned, 90-percent were aware of the iPhone, 32-percent who do not currently own the cellphone stated that they intend to buy one, and 8-percent of those envisage doing so in the next three months. Twenty-two percent saw buying an iPhone figuring highly at "some time in the future," possibly in a nod to the predicted software upgrades many believe will iron out the few omissions reviewers have highlighted.

Further analysis indicated that the 18 to 24 age group is most enamoured with Apple's new baby, with 40-percent intending to buy one at some point in the future; they were followed by the 25 to 34 group and 35 to 44, with 36-percent and 33-percent intending a purchase respectively. The under-45 population were more taken in general with the iPhone than their older counterparts.
