I need some expert advice. I have ordered an HP ZD8000 notebook computer. It was supposed to ship today, after ordering it 1 month ago. I received an email from HP. They ran out of my hard drive I ordered. An 60 GB 7200 Hard Drive. They want to replace it with a 80 GB 5400 Hard Drive and give me an extra discount on my computer. Would there be a noticable difference between the 2 drives. Note this is a media center notebook. Help. I need to let them know soon.
