Here's a good pic that shows both sides. You can see that the right side has a collapsible Gigabit Ethernet port, a full-sized HDMI port, another USB port, and what looks to be an awkwardly-placed cable lock facility.
The ENVY Spectre XT also has four speakers and Beats Audio processing and its keyboard is backlit. It's also pre-loaded with full versions of Adobe Premiere Elements 10 and Adobe Photoshop Elements 10.
It has a starting price of $US999.
