Hello everyone, I am new here. I currently own a 17" macbook pro that I use for video editting (weddings etc.) One of my buddies has aa 20" Imac G5 1 gig, 2.1 GHZ processor and 250 GB hard drive. He is offering it to me for $200? Would you make the purchase or try to get a G5 tour that can be upgraded more? I would be using this for video editting.
