Comparative Laptop Reviews?

clambert asks: "A few co-workers and I are in the market for a new laptop, but it's been incredibly difficult to try and explore what's out there. How do Sony's warranties rank up against Dell's? Can I get Wi-Fi and Bluetooth on the new Toshibas? What model IBMs feature DDR memory? There doesn't seem to be an AnandTech/Ars/Toms for the notebook market, and short of filtering through all the marketing hype on every {brand}.com, its tough to find out what systems offer what specs. Are there any comprehensive resources out there for those of us in the market for a new laptop?"
