Intel's Braswell and Cherry Trail 14-nm SoCs can make for PCs that sip power and are still fast enough for basic computing needs. Asus just pulled the wraps off of a pair of Transformer Book systems built around these chips running Windows 10, and the company says they'll run all day.
The Transformer Book T100HA is a svelte two-in-one notebook with a quad-core Cherry Trail-based Atom x5 Z8500 fed by 4GB memory and 64GB of eMMC storage. Storage is expandable with a micro SD card. Those internals sit behind a 10.1", 1280x800 IPS display in the tablet portion of the device, which attaches magnetically to the keyboard dock.
Peripherals can connect through USB 3.0 Type-C and micro HDMI ports in the tablet and a USB 2.0 Type-A port in the keyboard. Wireless connectivity is provided by 802.11n Wi-Fi and Bluetooth 4.0. There are a pair of cameras in the tablet, too—a five-megapixel rear shooter and a two-megapixel selfie cam in the front.
Working all day should be a possibility, thanks to a claimed 12-hour battery life. If you forget to charge the battery, Asus says the Transformer Book T100HA can charge from empty to 80% in just two hours through the micro-USB port. That 80% charge should keep the system going for about 9.5 hours.
If you'd rather keep everything together, the Transformer Book Flip TP200SA's 1366x768 IPS display folds around a full 360 degrees. The guts include a dual-core Braswell Celeron N3050 and the same 4GB of system RAM and 64GB of eMMC storage as the T100HA. As with its tablet sibling, the storage can be expanded with a micro SD card. The battery life isn't as generous in the Flip, though, with Asus stating you'll be able to go off the charger for up to eight hours.
The Flip has plenty of external connection options. Two USB 3.0 ports, one Type-A and one Type-C, and one USB 2.0 port adorn the sides to attach peripherals. Micro HDMI provides a connection for a second monitor. The wireless options are a little more capable than the tablet's. This convertible has 802.11ac Wi-Fi and Bluetooth 4.1. A single "VGA" front-facing camera is provided in the Transformer Book Flip TP200SA, which is quite a step down from that of the Transformer Book T100HA.
Both Transformer Books will be available later this month from the Asus online store and select retailers. Despite the fancy colors on the linked product pages, Asus is keeping the US releases subdued. the T100HA will come in any color you want so long as it's gray, and will set you back $299. The TP200SA will be available in dark blue for $349.
