Not enough Envy laptops to choose from? You\'ll also find a new thin laptop that HP has dubbed the Sleekbook. With a thickness of 0.8 inch and a weight of less than 4 pounds, this laptop could easily qualify as another Envy Ultrabook. But the Sleekbook does have a unique configuration of options and features, including optional discrete AMD graphics and a choice of black or red for the slip-resistant base. According to HP, the Sleekbook starts at $600 for the 15.6-inch model (available on June 20) and $700 for the 14-incher (available on May 9). The counterintuitive difference in prices reflects the fact that the laptop with the larger screen is configured with an AMD processor, while the one with the smaller screen has an Intel CPU.
