Tablet computers and computers.
To begin with, the table shows an interesting difference between the tablet computers and personal computers sales. The sales in 2010 for tablet computers were 19 million units compared to 346 million units of personal computers, showing the big popularity of these products. In the next year both increased their sales but personal computers still had the highest sales per unit. That can be confusing if we look directly at the table because it shows the 84% of tablet computer sales increase in comparison for the 2% of personal computers, this percentage throws the tablet computers as the best sellers of 2011.
Conclusion
It appears that despite the fact that tablets have the greatest increase in sales, this is not the most sold product, mobile phones have that position even though it suffered a decrease. However, it can be observed that smart telephones and computers will continue to increase their sales, and that personal computers maintain a somewhat frequent sales level.
