Research In Motion is getting ready to unleash the BlackBerry PlayBook tablet on the world. It’s been in the making for years but unfortunately their chief marketing officer has decided to leave the company. Keith Pardy joined RIM in 2009 but for “personal reasons” he’s parting ways. Pardy will stay on for the next six-months and transition himself out while a replacement is found. Not the best of timing for our famed Canadian tech company.
