I have the E1705 and the build quality is nice. The only complaint I have is that the paint will scrape where your palms go if you use that as a mouse surface. It's 2" thick and 8lbs. Lighter than my 15.4" toshiba satellite.
I agree that more choices on video cards would have been nice. I, however, wanted the power of the 7900GS so that was the reason I bought a Dell. If you go to costco.com and visit the HP builder, you will save a couple hundred dollars on the build (if you are not a member, there is a 5% upcharge - but compared to the HP builder there was a $200ish difference) provided they offer the dv9000. I was there two weeks ago when I was purchasing (they almost had me w/ the dv8000t and if I could have gotten a better video card I would have pulled the trigger) and only saw the 8000 model.
People are down on Dell. I must admit, for several years I was as well. I was a technology manager for Kinko's for a couple of years and I saw a million laptops come through the door. Dell did nothing to inspire me, let me tell you. But as I started looking, I quickly realized that smaller laptops don't give you much performance. Having recently purchased a 2007FPW as a second monitor, I was very impressed with it's display so I decided to give them a shot. I really like this laptop. There could be better ones out there but I found the most GPU for the money at Dell. $525 off a $2100 laptop. I just wish I lived outside of Texas because tax was murder. The response has been fantastic. People are in awe of the screen and when they see I can keep it in my lap and play BF2 with no lag (and no hole burnt in my jeans), they are even more amazed. My afore mentioned toshiba had a P4. You literally could not have it in your lap. This Dell, even though bigger, is cooler, lighter, and more powerful.
