Lenovo Yoga Tablet 2 AnyPenLenovo isn't content to rest on its laurels with the Lenovo Yoga 3 Pro. It just released a slew of new PCs for 2015, including new desktops, laptops, members of the Yoga family, and a pair of LaVie Z ultraportables that weigh about 2 pounds.

The Lenovo LaVie Z ultraportables are produced in collaboration with NEC Personal Computers. NEC was a pioneer in personal computing in the 1980s, but we haven't seen a U.S.-market PC from the firm in over 10 years. The LaVie Z HZ750 is a convertible hybrid laptop with a hinge similar to the Yoga line of convertibles. Lenovo claims that this is the lightest 13-inch convertible PC at 2.04 pounds, while the LaVie Z HZ550 is its 13-inch ultraportable laptop counterpart that comes in at an even lighter 1.72 pounds. Lenovo LaVie ZBoth ultraportables are only 16.9mm thin, using a magnesium-lithium body construction and back cover. A 13.3-inch WQHD (2,560-by-1,440 resolution) screen is an option, as is a fifth-generation Intel Core i7 processor and 128GB of SSD storage.

The LaVie Z HZ550 will start at $1,299 and the LaVie Z HZ750 has a base price of $1,499. Both will be available in May.

The 8-inch Yoga Tablet 2 with AnyPen technology lets you use any pen or pencil on the touch screen instead of your finger—specifically, any rounded metal or graphite point larger than 1mm in diameter. The tablet will be available in January starting at $299.

The 14- and 15-inch Flex 3 models offer up to fifth-generation Core i7 processors while the 11-inch tops out with an Intel Pentium. All Flex models come with 1,366-by-768 resolution screens, but the 14- and 15-inch models have full HD options. The Flex 11-inch ($399), 14-inch ($549), and 15-inch ($579) will be available in May. The Lenovo S41 is a traditional thin and light laptop, with a 14-inch screen, up to a fifth-generation Core i7 processor, and optional Nvidia GeForce graphics and 256GB SSD.
