A quick Nokia (NYSE:NOK) roundup: 1) Strategy Analytics says "extensive channel checks" indicate Nokia won't launch a tablet at the Feb. 25-28 Mobile World Congress. There are plenty of rumors about a Nokia tablet arriving this year. 2) Engadget's Mat Smith likes the potential of the Lumia 620, particularly in emerging markets (it goes for an unsubsidized $249 in China). The quality of the 620's hardware and UI give it a chance to appeal to first-time smartphone buyers in spite of Windows Phone's app shortage, he argues.
