Lenovo upgrades two of its popular Windows 8 “multimode” devices: the Yoga 2 Pro and the new refined ThinkPad Yoga, which is a laptop designed specifically for business users.

The biggest surprise comes in the Yoga 2 Pro, this new Windows 8 PC features a stunning screen resolution of 3200 x 1800, which is definitely better than the previous 1600 x 900 display. And of course it features Lenovo’s unique 360 degrees flip hinge. The device carries a 13.3-inch QHD+ display with 10-finger touch screen support and 16:9 aspect ratio. For what I’ve been reading the Yoga 2 Pro has a great viewing angle at 178 degrees.

Lenovo’s latest ultrabook upgrade is also powered by an Intel Core i7 Haswell processor, the choice to bump the storage up to 512GB SSD, 8GB of RAM, Intel WiDi for delivering content without cables to a TV, Dolby Home Theatre v4, and — listen to this — 9 hours of battery life, yes, that’s right! Full day battery sounds great and it even makes me think how many people will choose this device against the upcoming Surface Pro 2, which will offer up to 7 hours of battery life.

The new Yoga PC is also thinner and lighter than the previous version, now it’s only 15.5 mm thin and 3.06 pounds. Thanks to its original hinge technology design, users are able to work or entertain in 4 different modes: laptop, tablet, stand, and tent.

Finally, the new Yoga PC will feature a new backlit keyboard and it comes in Grey or Clementine Orange color.

Price is pretty reasonable at $1,099.99 for the Core i5, 128GB SSD, and 4GB RAM. and it will be available in October just in time for Windows 8.1.

ThinkPad Yoga

The new ThinkPad Yoga features the same hinge design as the Y2P, but it’s really customized for business people. This is a 12.5-inch magnesium alloy with the choice of Corning Gorilla Glass HD IPS or a FHD IPS display, and it runs Windows 8.1 — stylus pen is available.

Also the new ThinkPad is powered by a Core i7 Haswell processor, comes with up to 1TB of storage (which I can only assume is traditional rotating platter hard drive), backlit keyboard, 10-point multi-touch display, security features, security features like TPM and Intel’s vPro, and Lenovo claims “all-day battery life”, but the only downside compared to the Y2P is that the ThinkPad Yoga has a lower resolution 1080p (1920 x 1080) display.

An interesting feature is the “lift and lock”, a mechanism that pushes the keys inside the device is in tablet mode. So no more uncomfortable key feelings when you flip the screen around. For some strange reason, this isn’t a feature in Yoga 2 Pro.

Price start at $949 and it will be available in November.

Flex 14 & 15

Finally Lenovo is introducing two more affordable laptops, these are the Flex 14” and 15”, both have the choice of Intel’s latest Core i7 Haswell processors. The laptops aren’t close to be as sleek devices as the new Yogas or thin and light, but for a starting price of $629.99 for the 14-inch model and $829.99 for the 15-inch model, they are good options for people on a budget. They also feature “dual mode” which let you flip the screen 300 degrees for stand mode. By default both models will feature a 1366 x 768 screen resolution with the option of 1080p, Nvidia discrete GT 740M, and up to 1TB of storage with optional SSD or NAND flash.

Price starts at $629.99, as I mentioned earlier, and they will become available starting at the end of September.

What’s interesting about Lenovo’s new lines of Windows 8 PCs is that none of them offer Windows RT and this is because the company believes there is no need for such operating system. Execs claims that Intel’s Haswell chips are good enough to offer great battery life, performance, but more importantly they can offer a full-blown version of Windows 8 where people aren’t limited on the applications they can run.
