Many sources that the future investigates at present tablet will be a "companion device." Do you hear that before? Oh that rights the unfortunate Palm Foleo. The "best idea" Palm creator ever had been given up after its statement but before a single product was ever ship.
Why did Palm reject the Foleo? For the same reason RIM will find out soon sufficient companion devices doesn’t really makes sense. BGR says the BlackBerry tablet won't have its own mobile connections so it will only be useful by a Bluetooth connection to a BlackBerry or Wi-Fi.
So it's essentially an extra display for a BlackBerry that will have some multimedia functions, as well as reading e-books, Web browsing, and picture.
As to the statement, the device is programmed to dispatch by December. But right now we are not holding our breath here.
