Well, Apple have now killed the Mac Mini in New Zealand.
The 320Gb Mac Mini is the exact same price as the white Macbook. While the Macbook only has a 120Gb HDD, all the other specs are the same and I know which one I'd rather spend NZ$1848 on.
Is it the older chipset in the Macbook (it lists DDR2 ram).
In the UK the cheap Macbook is only £70 more expensive than the top Mini.
Cheap Mini looks to be the way forward (especially if 2gb+ gives you more video ram)
