From http://shawnblanc.net/2009/06/mac-setup-jon-hicks/, describing his setup, Jon Hicks commented:
"I still own a 1st generation MacBook Pro, as well as a last generation G4 Powerbook and 1st generation Titanium Powerbook. The Titanium is held together by stickers (I lost all the screws), and the stickers help prevent electric shocks from the coating that has been rubbed away on the top!"
My first thought was "Still, huh? That's what I currently use!"
I guess my system is crap, if I haven't moved on yet.
