LG has two new Windows 8.1 PCs at the Consumer Electronics Show this year. Its second Tab-Book 2 increases the 11.6-inch screen resolution to 1920 x 1080 and adds Intel Haswell processor options. The display is spring-loaded and slides down to cover the keyboard, converting it into a tablet. But if you’re also hoping to use this as a laptop replacement then you’ll need a separate mouse, as there’s no trackpad or pointing stick. The display is bright and has reasonable viewing angles, and a button at the side switches it into a reading mode that reduces battery usage and dims the display and color output.

Like the previous version there’s a release button on the side to return it back into a traditional laptop and the screen glides into either mode. For a convertible Windows PC it’s relatively light at 2.3 pounds, and there’s also a Bay Trail version that’s even lighter at just 2 pounds. That seems to be the main area of focus for LG with its latest Windows PCs at CES: keep them light. Despite the lightweight frame, it still feels sturdy even with the complex spring mechanism. There are two USB 3.0s, a full-sized HDMI port, and even a micro USB connector.

The Ultra PC feels surprisingly light

The second new machine is LG’s Ultra PC. It has a 13.3-inch 1920 x 1080 display, Intel Core i5 processor, and full-sized HDMI port. It’s also incredibly light, and that’s the most impressive feature with this particular model. At 2.2 pounds it’s easy to pick up with one hand, but you won’t be able to use the other to control Windows 8, as there’s no touchscreen. LG has a number of color options, but a white model with white keyboard looked the best at the company’s CES stand today. Both models are expected to debut this year, but LG has not yet provided pricing or exact release dates.
