Summary:
I purchased a 4gig blue nano and its awesome. The screen is brighter the battery really lasts 24 hours. And its really durable I've drooped it twice already and It still has no scratches and works perfectly. Apple has really made the best flash player on the market.

Pros:
Bright screen, Long battery, durable, Search feature, small, thin, Doesn't scratch easy, Good pic quality, Factory headphones have awesome quality.

Cons:
Doesn't come with software in factory package (But you can get it free off Apple.com)
