Microsoft has announced that the Nokia Lumia brand is dead; there will be no more Nokia-branded Windows Phones. Instead, we'll now get Microsoft Lumia devices. It will be interesting to see how the Lumia range does, now that it has been fully excised from Nokia. Microsoft's (MSFT) latest Q1 2015 earnings, released yesterday, highlight that sales of Lumia devices were only slightly up over the last year -- and I doubt that the transition to Microsoft branding will help matters.
