After sleeping on Landry Fields’ couch most of the season, Jeremy Lin has finally found an apartment of his own.  And it’s a big step up from previous digs.  The penthouse  in the W Downtown New York  is on the 38th floor and has sweeping views of the Statue of Liberty.  The rent?  It had been listed at $13,000 a month, but rumor has it Lin was able to get a better deal.    Who’s ready for the first Lin-sane house party?
