Laptops have been getting smaller, lighter, and more focused on casual computing. There's nothing inherently wrong with that trend, but these tiny low-power machines aren't a proper fit for everyone. Some of us need more powerful machines to get work done, and so netbooks and Ultrabooks aren't even on the table. Thankfully, we found a deal at HP for $150 off of a 15-inch laptop with a quad-core CPU and dedicated graphics -- no need to pay retail for a laptop with some real muscle.
