This reveals a bit of HN's biases. The news here isn't what the story that made the front page earlier said - that MS paid nokia 250M to sell phones. Rather, the story is that Nokia succeeded and sold 19M phones. While this still isn't close to Apple's 37M, it's a solid indicator that MS and Nokia may be down, but are definitely not out.
The "Lumia" is actually 2 phones, one mid-to-high range and one low-to-mid range. I wouldn't be surprised if the lower end one sold more units.
