Have a look at the above table. Yes, there are more smatphones sold than notebooks, netbooks, tablets and desktops combined.
“In
 2011 we saw a fall in demand for netbooks, and slowing demand for 
notebooks and desktops as a direct result of rising interest in pads,” 
said Chris Jones, Canalys VP and Principal Analyst. “But pads have had 
negligible impact on smart phone volumes and markets across the globe 
have seen persistent and substantial growth through 2011. Smart phone 
shipments overtaking those of client PCs should be seen as a significant
 milestone. In the space of a few years, smart phones have grown from 
being a niche product segment at the high-end of the mobile phone market
 to becoming a truly mass-market proposition. The greater availability 
of smart phones at lower price points has helped tremendously, but there
 has been a driving trend of increasing consumer appetite for Internet 
browsing, content consumption and engaging with apps and services on 
mobile devices.”
While PCs and tablets registered a 14.8% growth, Smartphones registered 62.7% growth YoY. On the other hand, Android has 48.8% of marketshare  (2011 worldwide sales figures taken into account).
It will be interesting to see how smartphones and Android fare in 2012, given that tablet sales are rising and PC manufacturers are now targeting end-users with Ultrabooks.
