The best mobile workstations on the market combine incredible graphics rendering with top-notch processing speed and superior displays. Unfortunately, they also cost and weigh twice as much as most traditional consumer laptops. In other words: you're paying top dollar for what's under the hood and not for your ability to easily transport the device from location to location. The mobile workstation market is led by machines like the Lenovo ThinkPad W540 ($2,573, £1,606, AU$2,946), a 4.4 pound, 15.6-inch, 2880x1620 (3K) resolution laptop with a 2.7GHz Intel Core i7-4800MQ processor and a Nvidia Quadro K2100M graphics card. Also at the top of the food chain is the Dell Precision M3800 ($1699, £1299, AU$2138), a 15.6-inch powerhouse that was recently updated to include a 4K monitor, an additional terabyte of data, Thunderbolt 2.0 docking and the option of installing Ubuntu. Like the previous model, the 4.4 pound Precision M3800 comes fully-loaded with NVIDIA Quadro K1100M graphics and an Intel Haswell Core i7 processor.If you're looking for something brawnier and more powerful, Dell also has the Precision M6800 ($3,490, £2,075, AU$3,750), which will cost significantly more, and crack your back at a gigantic 8.8 pounds. Not to be outdone by its competitors, HP has updated its ZBook 17 mobile workstation ($1900, £1250, AU$2400), a ferocious laptop built to withstand any task you throw its way. DesignThis 17.3-inch mobile workstation is built with a three-spindle wedge design that shifts most of its hefty 7.42 pound weight toward its thick backside (1.57 inches).
