Buy a Mac if you can't wait for an Amiga, you will enjoy it.
Never!! I like using Workbench because it´s fast, system efficient and allows the user to have more control over whats happening. MacOSX have none of these attributes whatsoever.
MacOSX is just a bunch of fancy, overdesigned graphics with none of the configurability that the Amiga has (or even Windoze). And you got to know illogical Unix commands to be able to use the MacOS CLI as well...
As long as I can get Windows for free or even Linux, I´ll rather stick with that! :-P
