This article questions the move but Samsung is one hell of a conglomerate that already sell over 50 different phones over 4-5 OS's. The Blackberry brand is still very valuable, the BBM and QNX/BBX tech both seem like non-terrible investments and yeah it does diversify their options should Googarola start to get favored.
I've always said RIM should have switched to Android keeping the Blackberry brand with a strong BBM based UI layer. I still think they should but maybe they need to totally hit rock bottom and have someone like Samsung step in and make the burning platform decision.
