Even though we risk repeating ourselves, the Refurb is full each day. Certain products are really interesting such as the white MacBook 9400M at 729 euros or the iMac 20" at 829 euros.
Take the time to make a comparison between the products and new items. Thus, Macbook Unibody can be less expensive than the Macbook Pro 13", but it will not have a high capacity battery nor Firewire. Similarly, check with Macbook Pro Unibody 15 and 17". It will be necessary to choose between Refurb models with removable battery or the new ones, at the price sometimes will be close but without the extended battery life, but however with the possibility of extending it.
To finish, note that Apple proposes again the Mac Pro Nehalem with reductions proportional at their basic price but also of Macbook Pro Unibody 17" with a matte screen.
