Our research shows that more than 60 percent of professionals use multiple devices in the office, 50 percent to 100 percent of the time, and nearly 60 percent send files back and forth between a mobile device and computer at least three times per week (with nearly 20 percent doing so more than 10 times a week).
According to research by Forrester, 74 percent of employees have two devices that they use for work, and 52 percent of users juggle three devices.1
It comes as no surprise that with more than half of professional workers juggling three devices that we often resort to emailing files to ourselves. Flirting between devices is made much simpler with the assistance of dedicated connectivity accessories such as USB docking stations or switchable keyboards.
