A new survey says 87 percent of PDA-owning professionals bring the devices into their bedrooms, and 84 percent check them before going to bed and as soon as soon they wake up in the morning.

Eighty-five percent of business travelers say they sneak a quick peek at their personal digital assistants if they happen to wake in the middle of the night, and 80 percent check their e-mail before they’ve had their morning coffee, the new study by Sheraton Hotels found.

The survey of 6,500 professionals who make more than $50,000 a year, take two or more annual business trips and have a BlackBerry or mobile e-mail device, found that 81 percent say they’re working harder now than five years ago – and many are enjoying it.

More than a third of those surveyed – 35 percent – said if forced to make a choice, they’d stick with their PDA over their spouse, and 62 percent said that they love their little high-tech companions.
