By 2013, more people will be accessing the web from mobile phones than from PCs, according to analyst firm Gartner's latest set of predictions.
The company says that there will be 1.78 billion PCs in use that year, outstripped by the 1.82 billion install base of smartphones and browser-equipped feature phones.
"Websites not optimized for the smaller-screen formats will become a market barrier for their owners," claims Gartner. "Much content and many sites will need to be reformatted/rebuilt."
The analyst's new report also predicts that context - including location, presence and social interactions - will become as important to mobile services as search engines are to the web.
"The most powerful position in the context business model will be a context provider," says Gartner.
