As ha and lumia are enough. Nokia don't need to add yet another brand. However, the big issue nokia are doing is to adding lots of numbers after the name. This is hard for the guy on the street to remember. Nokia n900, lumia 900, nokia n8, lumia 800,lumia 920. Not sure how the user can recognize a device for what it is when all of them have simular name than add asha xxx to that. It's a mess

Pureview as an Exellent kickass name. It actually stand for somthing and nokia can build a brand around it, users knows what the brand represents.
