NEW YORK ( TheStreet) -- Nokia's ( NOK) announcement of the release of six new Windows-based Nokia phones and a tablet on Oct. 22 is actually more exciting news for Microsoft ( MSFT) investors than for Nokia's.Earlier this month, Microsoft agreed to buy almost all of Nokia's devices and license patents. The transaction is expected to close within the first quarter of 2014, and investors should regard Nokia's ongoing phone strategy as Microsoft's. Nokia may be going through the motions, but for all practical purposes, the new devices are de facto Microsoft products. Selling tablets has been the nemesis for Hewlett-Packard ( HPQ), BlackBerry ( BBRY) and Barnes & Noble ( BKS). Despite less than tenacious sales of Surface, consumers will soon have another tablet from which to choose. Microsoft may feel like it's pushing a rock up a hill trying to capture market share from Apple ( AAPL) and Amazon ( AMZN) in the tablet space, but it does strengthen Microsoft's competitive position with Google ( GOOG).
