Now you can get a not-quite-an-ultrabook from HP, too. The company has started taking orders for the Envy Sleekbook 6, a thin-and-light machine with a 15.6" display and one of AMD's new Trinity APUs. This is no ultrabook (largely because Intel holds a trademark on the term), but with a 0.78" thickness and a weight of 4.53 lbs, it's definitely much thinner and lighter than your typical 15-inch consumer laptop.
The HP Envy Sleekbook 6 config sells for $699.99 with a dual-core AMD A6-4455M APU, integrated Radeon HD 7500G graphics, 4GB of DDR3 system memory, and a 500GB 5,400-RPM mechanical hard drive. Connectivity includes dual USB 3.0 ports, HDMI out, 802.11n Wi-Fi, and Bluetooth. A 60 watt-hour lithium-ion polymer battery can purportedly keep the system running unplugged for up to nine hours.
Surprisingly, HP doesn't offer any customization options for the system. Instead, more demanding users may want to upgrade to the Envy Ultrabook 6, which costs $100 more and comes with an Intel Core i5-2467M processor as well as 32GB of solid-state cache. HP lets you deck out the Ultrabook 6 with discrete Radeon HD 7670M graphics and up to 8GB of RAM, too. Just like with the Sleekbook 6, though, you're stuck with a 1366x768 display resolution and a mechanical hard drive. (Thanks to Liliputing for the tip.)
