Today, Lenovo has announced two new convertible PCs – the YOGA 3 Pro and updated ThinkPad YOGA 14. The company also unveiled the YOGA Tablet 2 and the YOGA Tablet 2 Pro, which features a built-in tablet-projector. Starting with the new converibles, the YOGA 3 Pro is even thinner and lighter than the company's previous model, the YOGA 2 Pro. It shaves off nearly 17 percent of its predecessor’s frame as is only 12.8mm thin. And it also weighs 14 percent lighter than its predecessor at only 1.19kg. This was accomplished by using a new watchband hinge built from more than 800 pieces of steel and aluminum.

Lenovo’s engineers redesigned the original YOGA hinge so that it now has the same that it has the same degree of flexibility and flatness as seen in metallic watch bands – which is why they are calling it a "watchband hinge". The YOGA 3 Pro design comes in 3 colors: Clementine Orange, Platinum Silver or Champagne Gold.

The YOGA 3 Pro comes with a 13.3-inch QHD+ 3200×1800 display built with Gorilla Glass. The device can be operated in four modes – Laptop mode, Stand mode, Tent mode or Tablet mode. It is equipped with JBL speakers with Waves Audio that automatically adjust depending on what mode the YOGA 3 Pro.

On the inside, the YOGA 3 Pro is powered with up to an Intel Core M processor with Intel integrated graphics and up to a 512GB SSD for storage boasting 9 hours of battery life. It also comes with 802.11 a/c wireless.

The Lenovo YOGA 3 Pro will be available beginning at the end of October in Best Buy stores and www.lenovo.com starting at $1,349 (U.S.).

For those who prefer Android, Lenovo created the YOGA Tablet 2 in 8 and 10-inches as well as the new YOGA Tablet 2 Pro in 13-in running Android 4.4 Kit Kat in Platinum.

Lenovo's new YOGA Tablet 2 is available in 8-inch and 10-inch models powered by an Intel Atom processor. It includes the 3 original modes – Hold, Tilt, and Stand – as well as a new fourth mode called Hang. Hang mode lets users hang the device to display content. It also comes with a 1-year subscription of Office 365.

The tablets feature dual front speakers with cinematic Dolby Audio and Wolfson Master HiFi audio, an 8 MP rear camera, Intel Atom processors, a micro USB with OTG connection that lets users charge their phone and dual band speed WiFi with optional 4G supported by the Intel XMMTM 7160 modem.

The YOGA Tablet 2 with Windows 10-inch version will be available in late October in Best Buy stores starting at $399.99 (U.S). The 8-inch version will be available on www.lenovo.com in November starting at $299.99 (U.S.).

The new YOGA Tablet 2 Pro has been developed with Ashton Kutcher, who joined Lenovo as a product engineer a year ago. It comes equipped with a built-in Pico projector. The projector lets users turn inside walls into an instant TV or movie screen. Users can project a 16:9 high resolution image onto any surface for an instant 50-in theater experience.

Lenovo paired this technology for great video with high-quality sound by giving the tablet a first - an 8 watt sound system with a subwoofer. Its dual, large-chamber speakers are front-facing for dynamic audio, and a subwoofer on the back rounds it out with deep bass notes while Dolby Audio and Wolfson Master HiFi ensure a multi-channel listening experience.

The new YOGA Tablet 2 Pro features a QHD 2560x1440 screen and runs on the latest 4th generation Intel Atom processor. Also, for picture-perfect snapshots, it has an 8 MP rear camera and plenty of storage equipped with 32GB and up to 64 GB via Micro SD.

All the Android models offer optional 4G. These models come with Lenovo Premium Apps that let users share, sync and protect information on their tablet. SHAREit shares information instantly between multiple devices without network charges, and SYNCit backs up and restores contacts, SMS messages and call logs.

The ThinkPad Yoga 14 is powered by a Haswell-class Intel Core i5 processor, with integrated graphics in the base model. An Nvidia GeForce 840M mobile graphics processor is available as an option. Both configurations come with 8GB of DDR3L memory, a 1TB hard drive supplemented by a 16GB solid-state memory cache, a 4-in-1 memory card reader, two USB 3.0 connectors, and one USB 2.0 connector that serves double duty as a power port. And while its 14-inch IPS display is larger than last year’s 12.5-inch model, the Yoga 14 will remain limited to resolution of 1920x1080 pixels.

The ThinkPad Yoga 14 has a docking connector adjacent to this power port, so you can connect it to one of Lenovo’s desktop docking stations using a single cable. Lenovo says buyers can expect to get up to 8 hours out of its battery.

The ThinkPad Yoga 14 will be available at the end of October, but in basic black and exclusively at Best Buy, with prices starting at $1199.
