Buy.com offers the refurbished 4.9-lb. Apple iBook G4 1.33GHz 12.1" Notebook, model no. M9846LL/A, for $219.99. That's the lowest total price we could find for this refurb by $3, although we saw one last week with half the RAM for $20 less, since expired. Features include a PowerPC 7447a G4 1.33GHz processor, 12.1" 1024x768 LCD, 1GB RAM, 40GB 4200 rpm hard drive, DVD-ROM/CD burner Combo drive, ATI Mobility Radeon 32MB graphics, Bluetooth, 802.11g wireless, Mac OS X 10.4.2, and more.

Of note, a 90-day warranty applies, although it's unclear who supports it.
