About to buy a MAC, want some input on what to buy. To be mainly used for Graphic Design work: Photoshop, Illustrator, Quark, and InDesign. And some DVD ripping and the normal email, web surfing. I have it narrowed down to 2 systems. The 20" Imac G5 or the Dual 1.8 Powermac G5. Both will have at least 1 GB RAM when ordered. The problem I have is that I heard that the Imac's Superdrives go to the crapper after about 3-4 months. (Anyone else hear this?) Anyone with an Imac give me some input on how they run? I would love to save the extra money an go Imac if they will run all the apps smoothly, but will spend more to get a Powermac. Any advice will be greatly appreciated.
