What are the differences between the original iPod nano models?

Please note that all iPod models mentioned in this Q&A have been discontinued. The original iPod nano was replaced by the second generation iPod nano on September 12, 2006.

The original iPod nano models, now discontinued, are the same except for capacity. The models introduced on September 7, 2005 have 2 GB or 4 GB of Flash Memory, and the model introduced February 7, 2006, has 1 GB of flash memory and sold for US$50 less (US$149, compared to US$199 and US$249 for the 2 GB and 4 GB models, respectively).

The original iPod nano models, regardless of capacity, are "thinner than a number two pencil" with an "impossibly small" 3.5 inch tall, 1.6 inch wide, and 0.27 inch thick "iBook white" or jet black and stainless steel case and a 1.5 inch 16-bit color 176x132 (.168-mm dot pitch) "blue white" backlit LCD display.

All original iPod nano configurations provide 14 hours of music playback and up to 4 hours of photo slideshows with music. Each also has the same proprietary 30-pin "dock" USB 2.0 port and a standard headphone jack on the bottom of the player. Like the iPod mini before it, navigation is provided by a small "ClickWheel", which places pressure sensitive navigation buttons underneath the scroll wheel.

Unlike the full-size iPod 5th Gen models, the iPod nano models lack video out, and as a result, can display photographs on the internal display "loaded" from a computer, but cannot display photographs on a television or projector. The iPod nano also does not support the iPod Camera Connector or third-party solutions, so photos cannot be transferred from a camera either.

The software loaded on the iPod nano models includes the calendar, contacts, and notes software from previous models, as well as additional software functionality, such as a "Screen Lock" security feature, a stopwatch, and a "world clock".
