How is your computer holding up? The cold hard facts are begining to hit me, that the Rev. A is getting a bit old. Doesn't support Core Image, Cinema displays, or USB 2.0. My goal was to try and hold out for Dual-Core G4's or a G5 PB, but who knows when that will be. Anyone else getting the ich to upgrade? And if so, what are you considering. Something from the current lineup? Next minor bump or Major Bump?
