The two computers rock aluminium and magnesium alloy bodies with a subtle etched pattern on the keyboard tray and the 15's lid. They have MacBook-style clickable touchpads but still feature left and right mouse buttons, and a button to turn off the touchpad, built into the pad itself.
The Envy 15 is a mere 25mm thick yet crams in an Intel Core i7 CPU, four RAM slots for up to 16GB of memory, dual SSD hard drives and ATI Radeon HD 4830 graphics. The display resolution is 1,600x900 pixels. In the States that hefty hunk of laptop starts at $1,800 (£1,090).
The Envy 13 is predictably less powerful, offering the Intel Core 2 Duo SL9400, a 1,366x768-pixel display, ATI Radeon HD 4330 graphics, and supports an external DVD burner. Slightly thinner than the 15, it starts at $1,700 (£1,030).
The HP Envy 13 and 15 come in environmentally conscious paper-based packets, with the instruction manual on a bundled SD card. So you really can turn green, with Envy! We'll get our coat.
