Gartner Report - predictions

According to Gartner estimates:
The total number of PCs in use will reach 1.62 billion units in 2012, all of which are capable of Internet access, even if some are not connected.
By 2012, the combined installed base of smartphones and browser-equipped enhanced phones will exceed 1.69 billion units. From 2012 onwards, this combined installed base will be greater than the installed base for PCs.
Nevertheless, most users in 2012 will use a PC as their primary Web access device and their phone as a secondary access device. However, as use of smartphones spreads globally, they will overtake the PC as the most common primary device for Web access sometime in 2015.
