Smartphone interfaces still lack the technology suitable for more complex mobile broadband operations such as gaming, it has been claimed.
The smartphone market entered a new era with the development of the Apple iPhone, which featured a multi-touch technology enabling users to browse the internet more easily.
However, smartphones are still not as easy to use as other broadband devices such as laptops and PCs, according to Guillaume Largillier, co-founder of Stantum Technologies.
Commenting on the iPhone, he said: "Zooming in and out with two fingers is definitely smart. But what's beyond the smartness? What's beyond the pinch gesture?
"Smartphone interfaces are still not suited for the more complex operations, such as taking notes in real-time, editing documents, or gaming.
He added that moving between applications, such as different internet windows, was far easier on a laptop than on a smartphone.
O2 has made a Pay & Go version of the iPhone 3G available, which includes unlimited Wi-Fi broadband browsing during the first 12 months.
