RIM's (Research in Motion) tablet device, the Blackberry Playbook, released in 2011. Pre-dating this is RIM's personal communication device, the Blackberry, which came to be known as the Crackberry because of the addictive behavior that it inspired in users.

Even on the verge of first release, the Playbook had already picked up the Crackbook nickname. Maybe it's because when it comes to saying,

- "Crackbook"

- "the new RIM Playbook personal tablet device"

the nickname crackbook just saves you time and life.
I need apps for my Crackbook.
