I am seriously considering purchasing a new 15" 1.5GHz PowerBook with SuperDrive. I expect that I will keep it for several years at the very least, so I'd like to prepare it for any eventuality. Can you help me decide which options would be most prudent to order with it? Here are my concerns: 1. 64 MB or 128 MB of Graphics memory (iDVD will definitely be used) 2. RAM? 512 MB in 2 (256 MB SO-DIMMs) or 1 (512 MB SO-DIMM)? 3. For Desk Top use? Additional Mouse and Keyboard? Any other accessories that I should consider? By the way, how reliable is the PC Card reader in the PowerBook? I will be using it to download digital photographs from a Type I Compactflash Card.
