There is a G4 MDD available locally, I believe I could get the package for close to $100. The ad reads in part... "G4 Mac Dual 1.42 GHz, 2 MB Ram, 150 and 40 GB Hard Drives/ 10.4.11 OS: comes with 17" Monitor, Apple Metal Keyboard and Dot Mouse." The monitor is a flat screen, (not Apple) and I have no idea what a "Dot Mouse" is. What's the consensus here? Also how much noisier might this unit be then my recently acquired 1.25 Ghz single MDD?
