I have a Dell Inspiron E1705 with a GeForce Go 7800 and I love it. A few months after I first received it as a graduation present, I lamented not upgrading to the TruLife screen, but after seeing how much glare there is on the TruLife screens, I learned to be content.
My dad bought a 17" HP laptop and it came with a full laptop keyboard--it includes a numpad like a regular keyboard would. If I had waited a few months, I probably would have asked for a HP instead of a Dell, but I'm still pleased with my decision.
Speaking of warranties, I have a four-year warranty on my Dell that expires May 2010, so I don't have to worry. That's especially nice since my desktop is starting to show its age and my notebook is now my gaming machine.
