I was thinking along these lines friday, when a first run Ti-Book came my way at work. It’s still beautiful, 1 gig of ram. On the other hand, the G4 inside is a raging 400 Mhz, and the hard drive is 10 gigabytes. At the moment, I’m using it as a clock, running Vladstudio’s wallpaper clock. I know, I know, I just hate wasting good, older hardware.
The cost of electricity for a year is probably more than the cost of a G4 on eBay.
