Within three days, Windows 8 will make its official debut to the tech world- an event which is awaited by the global IT community. On the same day, several computer manufacturers are also releasing their new gadgets capable of running on the new OS.

Below is a set of benchmark of changes between Windows products like XBOX and Windows Phone and competitive new features versus Mac and Linux.

Two of the manufacturers, Lenovo and HP, have recently announced their gizmos for Windows 8, the IdeaPad Yoga 13 and Envy x2, respectively.

Each has promising features and put new trademark technologies within their new products

The Lenovo IdeaPad Yoga 13 combines the productivity of an Ultrabook with the touch experience of a tablet, taking full advantage of the Windows 8 functionality. The screen flips a full 360 degrees into four modes that make it easy to create, share, or consume content. By combining those with its long battery life, Yoga 13 provides ultimate versatility for its user.

The new HP Envy x2 PC gives the power of two devices in one. A Windows 8 notebook with a bright, vivid HD Touch display and a tablet that slides off for those times when you want to carry even less.

The Lenovo IdeaPad Yoga 13 has four modes depending on the style you want to use it. It can be set as laptop mode which is convenient using Microsoft Office, tablet mode in case the owner wants to control it via user's hands, the tent mode for viewing while multitasking such as cooking, and stand mode for entertainment comfort.

The HP Envy x2 has two modes of usage. The first is as a notebook with its standard appearance for office, typing, and similar tasks and the second as tablet by separating its screen away from the keys for full and total control. The gadget has two separate batteries, one for each mode, to ensure that the user does not need to recharge so often.
