So many people are addicted to their BlackBerry wireless devices, that some have begun referring to them as the CrackBerry. Some users type on the mini keyboards so much that they’re developing a tendonitis condition referred to as BlackBerry Thumb.

The Sheraton Chicago hotel is trying to help visitors curb their addiction. They’ve offered to lock up the devices for guests who request it. The hotel’s manager suffered from his own addiction to the device and offers this service to help guests give up their device for a day or two in order to concentrate on their work.
