Just read a new estimate (10th June) of 900 million personal computers, plus all the corporate machines.
Amazing, but still behind cell phone penetration: 4 billions by
As of April 2002, 1 000 000 000 (one billion) personal computers have been shipped, and there will be 2 000 000 000 (two billion) by 2007; according to Gartner Dataquest.
However, Forrester Research says that in 2008, there were only 1 000 000 000 (one billion) personal computers IN USE. This is mainly due to the quick rate that technology becomes obsolete.
In 2012, there were 10.8% more computers sold than in 2011. In 2012 alone, 220 000 000 (220 Million, or 0.22 billion) computers were sold. Therefore, as of 2012, there are appropriately an additional 0.8 billion computers added to the total figure of personal computers in the world, with a slight reduction in the figure of those in use.
Total shipped: approx 2.8 Billion
Total in use: approx 1.4 Billion
