Apple's iPhone could emerge as the most succesful product introduction of the 21st century, new research suggests.

Lightspeed Research surveyed 39,000 people on its US online panel in the days following the launch of the device on 29 June - and the research findings are staggering.

Thirty-two per cent of those surveyed who do not currently own an iPhone stated that they do intend to purchase one, with 8 per cent planning to purchase in the next three months and 22 per cent planning to purchase "some time in the future", the researchers said.

Respondents ages 44 and under plan to purchase at a rate higher than those ages 45 and over. Forty per cent of respondents ages 18 to 24 said they are planning to purchase an iPhone some time in the future, followed closely by 25 to 34 year olds (36 per cent) and 35 to 44 year olds (33 per cent).

Apple has achieved notoriety for the device. Nearly 90 per cent of respondents have heard of the device.

Lightspeed Research claims those who live in the Pacific region were nearly twice as likely as those who live in other regions to purchase an iPhone. The New England and Mid-Atlantic regions also showed above average purchase levels.

In an additional survey of 34,000 respondents conducted by Lightspeed Research on 5 July, nearly half of those who would like to own an iPhone stated that the benefits of having music, movie, internet and wireless all in one was the top reason.
