RIM plans to shove the software in its forthcoming tablet under the bonnet of its BlackBerry line of smartphones.

RIM Co-CEO Mike Lazaridis told Reuters that the platform used in its Playbook tablet will also be used for a generation of smartphones that run more complex, multi-core processors. Lazaridis said that by focusing on the tablet market, Rim sees an opportunity to free where the smartphone can go.

When phones have multi-core processors they'll all be running the Playbook platform.  He did not say when this golden age would come about. RIM is launching the 7-inch PlayBook in the first quarter of 2011 it wants to sell between 2-4 million of them.
