3. Only 2X AGP mac. There are some older agp video cards that may only work in 2X slots so it is good to have the only 2X AGP mac around.4. 4 memory slots vs. 3 slots in the DA and QS actually give the Sawtooth a slight memory expansion advantage if you use OSX compared to the DA and QS.

5. Only G4 with a firewire port on the motherboard.

The Gigabit Ethernet also has 2x AGP and four RAM slots and line-in.(idk the specifics of the plaintalk mic though so will not comment)The gigabit ethernet may have lost the internal firewire port but it also gained gigabit ethernet on the back.

Aside from the onboard gigabit ethernet and internal 3rd firewire port.. I think the Sawooth and the GBE are pretty identical if you exclude that not all Sawtooth models can take dual CPU cards.

Actually, it would be neat to see someone drop the firewire hardware into a GBE, it has the pads for it.
