(Update May 25) The offer expired on late night May 22 when I was comparing N85 with Nokia 5800. However, one can find lightly used ones at eBay for about $230 to $250.
Found this Nokia N85 Reviews from theNokiaBlog: Nokia N85 Review – Part 1 The Physical; Top 5 Reasons Why Nokia N85 Is Better Than Nokia N96; Nokia N85 After 3 months – Build Quality Results (video below).
