The G1(1st generation) has mechanical buttons around the moving mechanical scroll wheel, with each stretching over one quarter of the outer circumference of the wheel. 
The Gen 1 iPod has a white plastic top plate around the FireWire port, headphone port and ‘Hold’ switch. 
ALL 5GB iPod are G1s. (M8513 Mac, M8697 PC). There was never a G2 5GB iPod. G1s weren’t only 5GB, however, since there was also a briefly available Mac-only 10GB Gen 1 (M8709).

The G2 (2nd generation) iPod has the same buttons as the Gen 1, but these are located around a non-moving, touch sensitive, solid-state touchwheel. The top plate is primarily stainless steel. The FireWire Port was protected by a built in cover. The G2s came with the remote and Apple case as standard. There was never a 5GB G2 iPod.

3rd generation iPods (Gen 3, G3, 3G, docking iPod)

The G3 (3rd generation, docking) iPods, also known as docking iPods, introduced a completely new form factor, with a single layer front (white plastic and lucite) and rounded edges front and back. The smaller body houses a smaller battery, of completely new design, with much reduced life.

The G3 iPod has four touch sensitive (backlit) buttons in a row above the non moving touchwheel. All G3 models have the new dock connector on the bottom, though the Dock itself is only included with the 15, 20, 30 and 40 GB models, and is an optional extra for the 10GB model, like the case and remote. The wired remote and headphone plugs have been separated, with separate sockets on the top plate, but remain integrated as one unit. 

All G3 iPods are Mac compatible ‘out of the box’. PC users will have to install and format the iPod for use on Windows with the included software. Even the biggest G3 iPods are thinner than G1s and G2s. (M8976 10GB version, M8946 15GB version, M9244 20GB version, M8948 30GB version and M9245 40GB version)

The body houses a smaller battery than G1/G2 iPods and is rated for up to 15 hours of charge, the most battery life out of any previous iPod models. 

The G4 iPod has four buttons around the touch wheel and an Action button in the center. All G4 models have the dock connector on the bottom, though the Dock itself is only included with the 40, and 60GB models, and is an optional extra for the 20GB model. The 40GB iPod and 60GB iPod photo does not include a wired remote. The wired remote and headphone plugs have been separated, with separate sockets on the top plate, but remain integrated as one unit.

Other iPod Models

iPod shuffle
The first iPod to not feature a screen, the iPod shuffle used the hookline “Life Is Random”, and is basically a thumb drive with Apples circular control wheel. A sliding off/loop/shuffle switch is located on the back of the iPod. The front features a two colour LED, which indicates various functions, above the play/pause/fwd/rev/volume up/down control.
A USB connector is located on the bottom of the iPod and covered by an end cap (the iPod’s capacity is engraved on the USB connector). The shuffle is flash based and is ideally suited for activities which might be considered too vigourous for hard drive based iPods.

iPod mini
Apple introduced the all metal iPod mini in January 2004 in one hard drive size, 4GB, but in five colors – silver, blue, pink, green and gold. Featuring the new style clickwheel the mini also makes use of the bottom docking port and headphone/remote ports and hold switch on the top plate. The black and white display is 1.67 inch.

A year later the range line up was changed to include models with a 6GB hard drive alongside the 4GB but one color was dropped from the mini family. The gold went and the remaining color range was made brighter and the clickwheel is now color coordinated to the main body color. The 1G mini is easily distinguished from the 2G as the latter has it’s hard drive size engraved on the rear. The mini was a popular choice amongst female iPod owners, with the pink always being the ‘hot’ color to have.

In September 2005 the iPod mini was discontinued, being replaced by the iPod nano.
