This deal has ended.
Apple.com now has factory reconditioned 4gb iPod Nanos in both black and white at their new $149 price point (they were $169). These 1000-song Nanos have the same 1-year Apple warranty that new iPods do. Shipping is free; sales tax is charged to states with retail Apple Store locations. For reference, new 4gb iPods are $199 at Apple.com. Also, consider both the Nike+ iPod Sport Kit (which only works with the Nano) and the Nike Sport Armband, both of which I own and recommend.
