• More than half of computing devices sold globally will not be PCs; smartphones, tablets and non-PC netbooks will outsell PCs. What does this mean for IT departments? Deloitte says, "The cost of managing a mixed network of both PCs and non-PCs is likely to be much higher than standardizing on one or the other." In this fragmented world, software and hardware will "likely require more customization, and developers may need to pick and choose which platforms they develop for, knowing that they cannot afford to address all markets simultaneously," Deloitte says.

• By the end of 2011, no operating system used on smartphones or tablets will dominate and become the standard. This is likely to mean higher costs for IT departments as they will have to support multiple more operating systems.

• In 2011 more than 25 percent of all tablet computers will be bought by enterprises, and that number will rise in 2012 and beyond. By the end of 2011, says Deloitte, a significant number of firms may be willing to pay for their employees' tablets and data plans. IT departments will have to decide whether to standardize on a single type of tablet or allow employees to choose their own devices. Costs will rise if organizations opt for freedom of choice.

What do you make of these predictions? Do you agree/disagree and how is your IT department planning to deal with multiple platforms?
