A new study by Robert Half Management Resources finds that your CFO likely cannot live without his cellphone.

The study surveyed 1,400 CFO’s from a cross section of U.S. companies and asked them “Which of the following portable technology devices do you consider most indispensable in your life? Their responses showed the cellphone to be their highest priority, with their laptops being a close second.

• Cell phone 44%
• Laptop computer 39%
• Wireless handheld 8%
• Mini hard drive 4%
• iPod 2%
• Other 1%
• Don’t know/no answer 2%

The most interesting result is that 2% of CFOs believe their iPod is their most important portable device.
