There has been a surge in demand for the upcoming iPhone 3G. RBC Capital Markets, the investment bank reports that more than 50% of people who intend on buying smartphones would choose an iPhone 3G.

After Apple’s annual developers conference, a survey was conducted involving 3,600 RBC Technology Adoption Panel members, and it was found that  more than 56% of the people had set their eyes on the iPhone.

RBC analyst Mike Abramsky says:

Overall intentions by the panel to purchase smartphones jumped to 10.5 percent, indicating a significant expansion of the smartphone market. The iPhone’s TAM (Total Addressable Market) handset share is expected to rise from 0.3 percent in 2007 to 1.7 percent in 2009.

iPhone’s competitors might claim to have better devices, but they have to strive to match Apple’s standard.The competition is still  picking up, but some many competitors have suffered scars and bruises already. Among them, Motorola stands out. The ChangeWave survey reviews show that Motorola has been losing its market share to the iPhone. With iPhone 3G coming, I wonder who’s next, after Motorola, HTC, with its Diamond Touch? Or RIM with BlackBerry? Maybe Treo?

Not much to predict there, actually. Precise details may vary, but it will be all of them, and many more.
