For those unfamiliar with the Lenovo Yoga brand, these flexible devices allow users to fold back its screen 360 degrees, turning a laptop configuration into a tablet configuration. For those who were familiar with the previous iterations of the Lenovo Thinkpad Yoga, having the keyboard mashing against the hand in tablet mode was widely considered a design flaw. Now, the newest 12 inch Lenovo Thinkpad Yoga has a mechanism that will extract the keys back down into the body when the screen is pushed back into tablet mode, so that the keys aren't raised, and won't be able to be depressed. Lenovo has named this innovation a lift and lock system.
Weighing in at 1.578 kg, this device is on the heavy side for tablet, which is why having the built in kickstand (the keyboard) will come in handy. Users can stand their screen up in tent mode or stand mode to move the keyboard out of the way. For a portable notebook, it is light and the 12.5 inch IPS screen is in Full HD which should ensure a good viewing experience. Under the hood is the 4th generation Intel processor which should allow for good battery life. The Haswell chips are available in configurations that go up to i7 which should facilitate a wide range of user preferences. A good selection of ports will allow for a variety of business and entertainment uses.
Intel HD Graphics 4400:
ULV integrated GPU (GT2) with 20 EUs found on certain Haswell CPU models.
Non demanding games should be playable with these graphics cards.

Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.
4500U:
Haswell-based ULV dual-core processor clocked at 1.8 GHz with Turbo Boost support up to 3.0 GHz. Offers an integrated HD Graphics 4400 and a dual-channel DDR3 memory controller.

This range of display format is largely the upper limit for tablets and the lower limit for subnotebooks.
The advantage of subnotebooks is that the entire laptop can be small in size and therefore easily portable. The tiny display has the added advantage of requiring little power, which further improves battery life and thus mobility. The disadvantage is that reading texts is exhausting for the eyes. High resolutions, which one is used to from a standard laptop, are almost not usable.
The same applies to tablets in this size range.
