NEW YORK ( TheStreet) --Dead soon after arrival: Microsoft ( MSFT - Get Report) pulled the plug on its teen-oriented Kin phones, adding to a growing list of product misfires for the tech titan.

Sales of the mod shaped, so-called feature phones at Verizon ( VZ - Get Report) failed to take off amid the hoopla surrounding the new round of smartphones from HTC and Motorola ( MOT).

Here are five takeaways from Microsoft's ill-fated Kin effort:
  • 1. Danger is dead. Microsoft's $500 million acquisition of the Sidekick maker two years ago was seen as an answer to Google's (GOOG - Get Report) Android push. Now the staff has reportedly been lumped in to Microsoft's Windows Phone 7 effort.
  • 2. Social networking isn't a killer app. The Kin phones attempted to capitalize on social media trends, with Twitter and Facebook built in to the phone's home screen. Tweets, it seems, can be done on nearly any phone.
  • 3. Verizon hearts Droid. Ask Palm (PALM) what a snub by the nation's largest wireless shop does for business. Verizon's Google Android franchise has a single-mindedness to it: Beat AT&T (T - Get Report) and the Apple (AAPL - Get Report) iPhone. Everything else gets lost in the heat of the battle.
  • 4. Microsoft is perilously adrift. The killing of the Courier tablet, the ouster of the top two product execs and now the killing of Kin suggest that maybe the strategy compass is spinning.
  • 5. Alternate take: Microsoft is eliminating the distractions and putting the focus on Windows Phone 7. Let's face it, mobile Internet-fueled computing isn't a passing fad. Microsoft's sudden, brutal decisiveness could be a sign that the Windows troops are gearing up for their Normandy.
