Windows 8 Consumer Preview may be available to download. however, if a person doesn't want to deal with installing a new PC OS to use something like its Metro interface, there is an alternative. Users of Google's Chrome web browser can download the recently released Chrome extension called MySites. It turns Chrome's tab page into a UI that looks very much like the Metro design, right down to its distinctive arrow logo on top.
The MySites add-on shows the most visited sites of a Chrome user and allows for a quick switch to the favorite sites section along with a section for your Chrome apps. All three selections can be edited with a quick click of the mouse. As you can see from the screenshots of my most visited sites above, they get bigger squares in proportion to how many times one visits a site. Some sites like Microsoft, Google, Twitter and Bing even show their logos in the squares.
However, if you use MySites for Chrome, be aware that the Search box in the middle of the various website tab boxes uses the developer's own Incredibar search engine and cannot be changed to Google, Bing or any other search engine. You are better off just searching via Chrome's own default search site.
