So ... this one in today ....

'Moto Splits'

Motorola today announced plans to split the company into two separate entites: Mobile Devices and Broadband & Mobility Solutions in a "structural and strategic realignment of its businesses".
“Our decision to separate our Mobile Devices and Broadband & Mobility Solutions businesses follows a review process undertaken by our management team and Board of Directors, together with independent advisors,” said Greg Brown, Motorola’s president and chief executive officer. “Creating two industry-leading companies will provide improved flexibility, more tailored capital structures, and increased management focus – as well as more targeted investment opportunities for our shareholders.”

The question is ... why ? Given that :

..... "Our priorities have not changed with today’s announcement” ... “We remain committed to improving the performance of our Mobile Devices business by delivering compelling products that meet the needs of customers and consumers around the world.”

Just don't why it needs to be done in two parts - doubtless wise commentators will weigh in soon.
