In the ever-developing tech world, hybrid devices have risen up the ranks and are taking the market by storm. At the forefront of the battle are the tablet/laptop 2-in-1 devices, which are arguably being led by Microsoft’s Surface Book i7 and Lenovo’s Yoga 910.

On October 26, Microsoft introduced the Surface Book i7 -- sometimes referred to as the Surface Book 2 -- which upgraded from its predecessor in relatively humble ways. The design is generally unchanged, though the new device is noticeably heavier and thicker. But while these traits are not ideal, the Redmond-based company has included enough features that more than make up for it.

The Surface Book i7 is at least 3.63 pounds and is thickest at 22.8mm. It does, however, come powered by the sixth generation Intel Core i7 processor and is partnered with the Nvidia GeForce 965M graphics chip. The discrete GPU and its cooling units are installed into the keyboard of the device. This means that once the display is detached from its Performance Base, the same power is not experienced.

Another improvement that Microsoft made for the Surface Book i7 is better battery life. The device can reportedly run for 16 hours on a full single charge while hooked onto the base and 12 hours when detached. Price starts at US$2,400 (AU$3,156) and it is available for pre-order at Microsoft.

The Lenovo Yoga 910, on the other hand, is powered by the seventh generation Intel Core i7 processor and an Intel HD Graphics 620 chip. The CPU proves that Lenovo did not cut any corners in terms of power, which is sometimes an issue with hybrid devices. The upgraded technology allows the CPU to work at its most efficient without overheating.

The company boasts that the Lenovo Yoga 910 will last 9 hours on a single battery charge, which is significantly less than the Surface Book i7. It does, however, flip over completely to turn into a laptop and notebook, unlike its Microsoft competitor that needs to be detached. The Lenovo hybrid's pricing begins at US$1,330 (AU$1,750).
