Fan of Nokia here, not Microsoft. The emotional attachment is with Nokia, not Microsoft. If future phones will be branded Microsoft Lumia or whatever the name be - then I don't think I will be buying them simply put. I want to own the brand Nokia, not simply Microsoft.
Owning the brand Nokia is not going to be an option, at least not in smartphones.
So, if Microsoft slaps a Nokia label on the phones, even though Nokia has no control over the development, than would you buy one? Nokia is just a name. While the name has history, the important factor isn't really that name. If MSFT continues to build with the same design quality and much of the same employees base, doesn't it make little sense to let your love of the name hold you back? What are your options? Will you now learn to love the names, Samsung, Apple, HTC, etc? Will moving on to one of those names be better than moving on to, what could still be, in essence, Nokia, but with a newer, shinier name? Sorry, but I don't see how the love of Nokia makes you go away from a brand that now encompasses everything that used to be Nokia, simply for the love of a name. If time passes and you don't think MSFT continues the things that made loyalists in the first place than I'd understand, but as of now, the new Lumia/Asha is the closest thing you'll be getting to what was once your beloved brand.
