Red rice Note 3 depth dismantling

The red rice Note 3 released on November 24th, as the first metal body of Xiaomi, and equipped with a fingerprint recognition function, will eventually bring the thousand yuan machine market into white heat. There were tigers and wolves before and after, and Lei Jun could not help but choke after feeling his years of working life. From "born for a fever" to "all my longings", from pragmatism to retreat, is this the pace of Lei Jun or Xiaomi? Red rice Note 3 is late, is it a big move for MI 5, or is it awkward to keep up with the rhythm of the market? Go into the red rice under the cold shell and see what is still hidden inside us to make us cry.
