The average desktop replacement weighs around 6.5 pounds or more, sports a dual or quad-core processor, at least 4GB of RAM and 500GB of storage, and plenty of connectivity. Unfortunately battery life is not one of their strong points due to the large display and powerful hardware, so most of the time you’ll be looking at around 3 hours of autonomy. Laptops in this category start at around $1,000 but fully-loaded models can easily fetch upwards of $1,500. HP Envy 17 HP’s Envy laptops earned some praise and criticism when they debuted last year for their similarity to Apple’s MacBook Pro lineup. Indeed, the keyboard design, quality aluminum construction and glossy full size display are all reminiscent of an Apple product, but unfortunately so where the sky-high prices. The new 17-inch variant builds on some of the strong points of this upscale line while also bringing several new hardware options to the table and more reasonable price points. This feature-packed multimedia monster includes a Blu-ray drive, HDMI and DisplayPort outputs, a 1920x1080-resolution 17.3-inch display, an Intel Core i7 720QM, a 1GB ATI Mobility Radeon HD 5850, a massive 8GB of memory, USB 3.0 support, and a triple bass subwoofer. With a starting price of $1,299, the Envy 17 is one impressive machine. Additional views:
