I agree with Atanamir on the Asus. If you decide Dell, don't go looking to the actual company for support. If you choose anything from HP, expect expensive repairs from the company and/or look for a small business around you to fix.
If you don't plan on gaming for the laptop, I suggest the mac probook. Even though I don't like macs, they are dependable, able to organize music and videos with ease, editing photos and videos, etc.
