Branding is hard. Branding is expensive.
And changing brands mid-stream is hard, expensive and sometimes (often?) ill-advised.
But according to known leaker @evleaks, Microsoft may be doing just that. According to his unnamed sources, Microsoft may be moving toward rebranding its Surface tablets as "Lumia" devices.
@evleaks also claimed that Microsoft may be negotiating to keep the Nokia brand longer than originally planned so that it can use it for future phones and possibly other devices.
Earlier this month, @evleaks published what looked to be some kind of Microsoft "technical branding" guidance document, which indicated that Microsoft planned to phase-out Nokia branding on a very specific schedule: 18 months post close of the Microsoft acquisition of the Nokia handset business for Lumia devices; through December 31, 2015 for Nokia X Android phones; and 10 years for Asha mobile phones. (From the way that planning document is phrased, I would guess it predated the close of the Microsoft acquisition of Nokia's handset business in April 2014.)
I don't have any first- or even second-hand information about these branding rumors. I've asked Microsoft but am not expecting any kind of comment.
