CES 2014: Lenovo unveils new additions to Windows 8.1 PC family

At CES this week, Lenovo announced several new Windows 8.1 PCs, including an ultralight 14in ultrabook and updates to existing innovative designs like the Yoga and Miix lines.

These systems are mostly portable, but the C560 touch-screen all-in-one desktop shows that major PC makers like Lenovo are still committed to innovative and traditional form factors.

The Lenovo ThinkPad X1 Carbon is the updated version of Lenovo's premium ultrabook, now in its third generation. Like previous models, the X1 Carbon uses carbon fiber in its construction for strength without the weight of aluminum and magnesium, resulting in a very light 1.2kg ultrabook. The new version comes in with a 14in screen, optional 4G connectivity, and a claimed nine-hour battery life. With connectivity to Lenovo's new OneLink Pro Dock, the X1 Carbon becomes a fully connected desktop with a one-plug link to power, USB, DisplayPort, DVI, and Ethernet. The ThinkPad X1 Carbon will be available later in January.

Lenovo's ThinkPad 8 (pictured above) is an 8.3in Windows 8.1 tablet with an Intel Bay Trail quad-core processor, up to 128GB SSDstorage, microUSB 3.0, and optional LTE networking. The tablet's 8.3in touch display has a 1,920 x 1,200 resolution display, so it's capable of displaying 1080p HD content and large spreadsheets equally well. The ThinkPad 8 can be equipped with an optional keyboard base for traditional desktop computing, or clip on the optional Quickshot Cover that will put the ThinkPad 8 in Tent Mode, similar to Lenovo's Yoga models.

Lenovo updated its Yoga line as the Lenovo Yoga 2. The Yoga 2 comes in two models; 11 and 13 inches. Both have the full range of motion that previous models had, with Laptop, Stand, Tent, and Tablet modes. The 11in model is 0.67in thin with a 1.3kg system weight, and features Intel Pentium processors. The 13in model is just a smidge thicker at 0.68in and weighs in at 1.5kg. The 13in Yoga 2 has a Full HD screen (1,920 x 1,080 resolution), fourth-generation Intel Core i5 processor, and SSHD option. The Yoga 2 11in starts is available later in January. The Yoga 2 13in will be available in February.

The Flex 14D and Flex 15D are AMD-powered versions of the IdeaPad Flex 14 and 15 laptops introduced last year. The Flex 14D and 15D also rotate into Laptop and Stand mode, but lack the Tent and Tablet modes of the Yoga 2 line. Both Flex models feature AMD A6 quad-core processors and AMD Radeon HD graphics. The Flex 14D and 15D are available now.

The Lenovo Miix 2 convertible laptop comes in two sizes: an ultraportable 10in and a performance 11in model. Both Miix 2 convertibles are detachable tablets with keyboard bases. Like the Lenovo ThinkPad Helix, the Miix 2 tablet portion can be carried around alone, clipped into the base in laptop mode, or flipped around and connected in Stand mode. The 10in Miix 2 features an Intel Atom processor, 10in 1,920 x 1,200 touch screen, up to 128GB SSD, and all-day battery life. The 13in model also has a 1,920 x 1,200 screen (albeit larger), but comes with a fourth-generation Intel Core i5 processor, and up to 256GB SSD. Both Miix 2 models come with a plethora of ports on the tablet and keyboard base, including SD card reader, micro USB, USB 2.0, micro SD, and mini-HDMI.

In the traditional laptop space, Lenovo introduced the Y40/Y50 andZ40/Z50 laptops. The Y40 and Z40 are the 14in models, while the Y50 and Z50 are 15.6in models. The systems have a wide variety of options, including up to fourth-generation Intel Core i7 processors for all four models, screen resolutions from 1,366 x 768 (Z40/Z50) up through 1,920 x 1,080 (Y40/Y50 std., optional on Z40/Z50), with optional UHD (3,840 x 2,160) available on the Lenovo Y50.

All four systems have Intel HD Graphics standard, but can be upgraded with discrete AMD Radeon R9 M270 (Y40), Nvidia GeForce GTX (Y50), or Nvidia GeForce GT 840M (Z40/Z50). All four can be equipped with up to 1TB hard drives, with a mix of hybrid SSHD and SSD options available. The Y40 and Y50 are aimed at the performance fans, with the Z40 and Z50 targeted at multimedia fans on a budget.

Last, but not least, Lenovo introduced the C560 all-in-one desktop PC with a 23in 1,080p full HD display and optional touch screen. The C560 has a wide variety of configurations, ranging from a value-oriented Intel Celeron powered model up to fourth-generation Intel Core i7. Nvidia GeForce 705A discrete graphics are optional. The system comes on a sculpted metal stand, so it looks very much like a 23in HDTV, and comes in glossy white or jet black. A DVD burner is standard, and up to 2TB of hard drive space is optional. The C560 is tool-less for memory and storage upgrade, which is notable for aconsumer all-in-one desktop.
