Deloitte predicts that in 2011, more than half of all computing devices sold globally will not be traditional PCs. Sales of smartphones, tablets, and non-PC netbooks are expected to exceed 400 million units, surpassing the almost 400 million PC units expected to be sold. While PCs will remain important, 2011 may mark the tipping point to a more diverse computing environment with at least two different chip architectures and five operating systems each having over 5% market share, as smartphones and tablets grow to represent around 25% of all computing devices.
