There's a household I am helping with their IT situation and they are presently exclusively Mac based with two iMacs... They are looking to upgrade to add one more workstation and I have suggested they should go for more power - maybe a G5. Another contact of mine has the Mac that is white with the dome under the screen (what model IS that?) and I am wondering if that is also an option for them. What do the Mac people here have to say, Speedy Dave? Techno? Others?
