The HP mobile workstation lines were incredible, often coming with great displays (WUXGA; 1920x1200 17").. but they weighed a ton, and struggled to fit in most bags. Acer made some similar gaming rigs. I used to build product demos that didn't need internet access (you could easily load them up with 16gb memory and SSD's, and run multiple VMs with excellent performance).
