Lenovo is doubling down on its Yoga brand, unveiling a bunch of new tablets and laptops sporting the name today. The highlights were the Yoga Tablet 2 Pro, a 13.3-inch Android tablet with an integrated pico-projector, and the Yoga 3 Pro, a 13.3-inch Windows tablet with a 360 degree hinge that contains more than 800 parts.

Many of Lenovo's Yoga tablets have been a little unusual, as tablets go. Instead of simple cuboids, they've had a bulge along the bottom that's housed a hinged stand to prop the screen up. In the Yoga Tablet 2 Pro, this bulge is used to house a tiny projector that can cast a respectable 50 inch picture onto a nearby wall, so if the 13.3 inch, 2560×1440 LCD isn't big enough to watch a movie on, the wall may do the job.

The Android 4.4 tablet unusually sports a 4 core Intel Atom processor running at up to 1.86GHz. It pairs this with 2GB RAM and 32GB storage (with a microSD slot for adding another 64GB). Connectivity comes from dual band 802.11/b/g/n, and in some countries, optional 3G/4G. It has dual cameras; an 8MP rear and 1.6MP front device. The whole package weighs just over 2lbs. The battery lasts up to 15 hours on a charge. It'll be available from the end of the month starting at $499.

The new Yoga 3 Pro (pictured top) is a sleek laptop with one of Intel's new Broadwell chips. Lenovo's Yoga laptops were characterized by a hinge that folds all the way back, converting the laptop into a sort of tablet. The Yoga 3 Pro continues this trend, with a new hinge that Lenovo says is hand-assembled from 800 individual parts, and modelled after a watch band. Up close it looks extraordinarily elaborate.

The 13.3-inch screen has a 3200×1800 resolution, and is coated with Gorilla Glass. The Core M-70 processor is a 2 core, 4 thread part which can run at up to 2.6GHz. It is matched with up to 8GB RAM, and up to a 512GB SSD. Connectivity comes from 802.11ac and Bluetooth 4.01, and there's a 720p camera. The system weighs a svelte 2.62lbs and is half an inch thick. It runs for up to nine hours per charge. It too will be available at the end of the month, starting at $1349.

As well as these flagship devices, Lenovo announced a quartet of Yoga Tablet 2 tablets. These tablets all have the same basic specs: a 1920×1200 screen, 4 core Atom processor at up to 1.86GHz, 2GB RAM, 32GB storage, dual band 802.11b/g/n Wi-Fi, 8MP rear and 1.6MP front cameras—with two different screen sizes (8 and 10.1 inches), and two different operating system choices: Windows 8.1 or Android 4.4. The 10.1-inch systems also have optional 3G/4G. The Android versions will cost €229 and €299, available immediately; the Windows ones will cost €249 and €399 and are available later this month. The 10-inch Windows version includes a Bluetooth keyboard; this will be available as an option for the 10-inch Android version. Battery life is claimed to be up to 15 hours for the Windows versions, and up to 18 hours for the Android ones.

The company also announced a business-oriented ThinkPad Yoga 14. This doesn't have the fancy hinge of the Yoga 3 Pro, and isn't super thin either, at 0.7 inches thick. Equipped with Haswell processors, it has a 14-inch 1920×1080 display, optional Nvidia GeForce 840M discrete graphics, a 1TB disk with a 16GB SSD cache, and will weigh 4.1lbs. It will be available at the end of the month, with prices starting at $1,199.
