After being one of the first to get a RevA 17" PowerBook, 1GHz, with 1GB of RAM, I'm ready for a computer upgrade. I'm torn between two options, and two main benefits--performance vs. portability. Here's what I'm thinking about: 17" PowerBook $3473.00 2GB DDR333 SDRAM - 2 SO-DIMMs 100GB Ultra ATA drive @ 5400rpm 8x SuperDrive (DVD±RW/CD-RW) AirPort Extreme Card Backlit Keyboard/Mac OS - U.S. English AppleCare Protection Plan for PowerBook (w/ or w/o Display) 1.67GHz PowerPC G4 ATI Mobility Radeon 9700 (128MB DDR) 17-inch TFT Display Subtotal $3,473.00 Dual 2.0GHz PowerMac G5 w/20" ACD - $3323 2GB DDR400 SDRAM (PC3200) - 4x512 Dual 2GHz PowerPC G5 250GB Serial ATA - 7200rpm ATI Radeon 9650 w/256MB DDR SDRAM Apple Cinema Display (20" flat panel) Bluetooth Module + AirPort Extreme Card 16x SuperDrive double-layer (DVD+R DL/DVD±RW/CD-RW) Bluetooth Module + Apple Wireless Keyboard & Mouse - U.S. English Mac OS X - U.S. English AppleCare Protection Plan for Power Mac (w/ or w/o Display) Subtotal $3,323.00 Also, is there a huge difference between the Dual 2.0, 2.3 and 2.7GHz speeds that might be worth the extra $$? Decisions, decisions. I'm so used to being able to take my computer with me that it would be difficult for me to part with the portability. However, the amount of travelling I do has decreased dramatically. And, with the 1.67GHz G4 to the Dual 2.0GHz G5, it seems like the perfomance gain might be worth it. I do a lot of graphic design with Adobe Photoshop, NON-HD video editing, and Audio Production (DigiDesign ProTools, Logic, etc.). What would you do in my shoes?
