* Lighter than the Macbook (but there's not much in it)
* Same screen resolution (1280x800)
* Slot-loading disc drive, but with a DVD Writer
* Nvidia 8400M compared to Intel X1300 graphics
* Had 1gb more memory
* Had 40gb bigger hard disk drive
It does, however, lack 802.11n, and the Macbook is marginally prettier. The kicker is that the M1330 was £130+ cheaper than the Macbook equivalent even after factoring in the educational discount.
There really is no way of spinning it - Apple's hardware is, and always has been, comparatively expensive, and in exchange you get Mac OS X. Apple has never competed on price. If one day I can afford to spend £700+ on a laptop I'd certainly consider buying a Mac but until that point I'm happy with my mid-spec PCs.
