The phone's OS is its biggest limitation
Whether or not the smartphone will bring Nokia back in the major league however is a whole different story. And just like the time when we had the Lumia 800 around for a review, we can't give you a definite answer. One thing is certain though - Nokia is still a long way from the top in this important segment, but they've got their eyes on the stars, and they seem determined to succeed. The Lumia 900 is a nice step in the right direction.
