I have 3 macs, A powerbook, a g4 tower, and a mac mini. I bought the Apple monitor for a grand back in the day for my g4, my mini runs on a nice vga aftermarket monitor and is fine. I am really close to getting a new mac pro but I don't know if I can justify a grand for the monitor. I know they are very nice, but can you use any monitor brand for the mac pro?
