A A 10.4 available again for pre-ordering up on Amazon. Rich Trouton Mar. 28, 2005 - 11:39 AM PDT Mar. 28, 2005 - 11:39 AM PDT 1 Comment As reported earlier, Amazon is offering pre-ordering for 10.4 with a rebate of $35. However, at the time of the previous entry, Amazon pulled the ability to pre-order 10.4 from its website after having it up. Now, pre-ordering has been re-enabled. Hopefully, it’s back to stay.
