Analysts at Strategy Analytics predict that the Apple iPhone will grab as much as 10 percent of the US smartphone market by the end of 2007.
According to Strategy Analytics' Neil Mawston, 2 million smartphones will be sold in the US during 2007.
Mawston said: "We expect Apple and its iPhone portfolio to account for 2 million of that total, giving it a 10 percent share by the end of the year."
Speaking about the potential success of the Apple iPhone, Strategy Analytics David Kerr said: "A critical question will be what percentage of iPhone buyers will be churning from other operators?
"A second key issue is whether the iPhone will draw users who would otherwise have bought Nokia N series music and multimedia devices, eroding their premium tier share, or will iPhone most dramatically impact the SEMC Walkman series fortunes?"
But Chris Ambrosio of Strategy thinks iPhone will deliver: "Apple has a strong brand and good retail presence; now it needs to deliver on the product. Competitive pricing, of course, will be critical, as will the device's usability and reliability."
According to Strategy Analytics, Apple's iPhone is predicted to create $1.4bn in new revenue for Apple.
