Compared to...? At this point, they've released three high end Windows Phone devices in the US. The Lumia 900 (Carrier exclusive) Lumia 920 (Carrier Exclusive) and Lumia Icon (Carrier Exclusive) There have been variants of these three phones released that were all carrier exclusives and ultimately, by the time they were released, they were mid-rangey at best. The only two that were up to par with modern specs were the Lumia 920 and Lumia Icon. The Lumia 920 did very well unless you compare it to something like Samsung and had the best Amazon user reviews I've ever seen from a mobile device and for several weeks was the highest selling device on Amazon. The Icon is a verizon exclusive. A carrier that is known to have 0 love for Windows Phone and was the first to introduce a hindrance to long-time Windows Phone users in the form of no Glance screen (Hardware restriction) that dissuaded the fans. Walking into the store or being a fan, you were met with a major dissuader. I feel that if a high-end Lumia got the same release as the M8, in that it hit all major carriers in the US, it would beat out the M8 as HTC's foothold in the market is barely the remnant of a footprint. Does Nokia sell well in relation to Samsung? Not close. In relation to most OEMs. They do very well.
