iPod Range Rated on Price, Capacity and Size
I've done an odd, but maybe useful, pricing table for iPods.
It is in UK prices, and the interesting column is the Price/GB/cm^3 one.
512MB Shuffle
Price: £69
Price/GB: £138
Volume: 16.8 cm^3
Price/GB/Volume: £8.26/GB/cm^3
Capacity-Volume Value: **
1GB Shuffle
Price: £89
Price/GB: £89
Volume: 16.8cm^3
P/G/V: £5.29/GB/cm^3
Capacity-Volume Value: ***
2GB Nano
Price: £139
Price/GB: £69.50
Volume: 25.2cm^3
P/G/V: £2.75/GB/cm^3
Capacity-Volume Value: ****
4GB Nano
Price: £179
Price/GB: £44
Volume: 25.2cm^3
P/G/V: £1.74/GB/cm^3
Capacity-Volume Value: *****
20GB iPod
Price: £209
Price/GB: £10.50
Volume: 95.2cm^3
P/G/V: £11/GB/cm^3
Capacity-Volume Value: *
From the above: If capacity is all that matters, then the iPod clearly windos on the Price/GB, being 4x more price efficient than the next closest iPod! However if the volume of the player is most important, the iPod drops to last! The 4GB nano is astoundingly cheap per GB per unit volume. Way more so than the Shuffle, and you get a colour display and style to boot.
The worst buy is the 512MB Shuffle. It sucks on a capacity rating, on the price per capacity rating, and on the price/capacity/volume rating. The 1GB Shuffle is nearly as bad. Clearly, if the choice is between a 1GB Shuffle and a 2GB Nano, the choice would be the Nano, despite being £50 more.
