My machine is a 2 year old 1.25 Ghz 15 inch PowerBook. I've got 1.5 GB of RAM and am considering maxing out to the full 2 GB soon. I've also installed a 100 GB 7200 HD, and that has made a huge difference in speed when dealing with photographic work now that they load twice as fast off of my HD.
Well, sounds like you're already in good shape as far as software and your computer! I'd definitely recommend maxing out your RAM on your PB. That in combination with your 7200rpm hard drive should be very effective in working with the new images you'll be putting into your computer.
stoid said:Also, advice on purchasing a used camera? I've seen used Rebels go for as low as $500, and I'm wondering if it's a good idea, or if I should buy new.
I would suggest that you buy new. That way, if there are any problems, the camera is under warranty and if need be you can get a free repair, replacement or whatever is necessary. These digital cameras are sensitive electronic equipment and it is all too easy for something not to be right, even straight out of the box.
If money is a consideration you might be able to pick up a new Nikon D70 for not much money, since that model was replaced by the D70s back in the spring. Ditto for the Digital Rebel, as Canon replaced its original DR with a newer version.
