For graduation I will be getting pretty much any computer I want that is under $3,500, courtesy of my Uncle. I already know it is going to be a laptop and I already know I want to wait until the new line with Leopard comes out. So its no questions on that, but more on accesories to it. 1. Is there a difference between the 20 and 20 inch Apple Cinema Display besides the obvious resolutions and screen size? 2. Is there any protective screens that don't detract from the appearance of the laptop? 3. While using the Wireless Mouse and Wireless Keyboards, does it take up a USB port for a base station or anything? 4. How can I hook speakers up to it? Right now I have some logitech speakers, can I use them with my laptop and ACD? Thank you very much.
