Good news for Windows users. It is called Windows 8.1 with Bing, is targeted towards OEMs and will allow them to build lower-cost Windows devices.
According to Microsoft:
As we move forward, many of these lower cost devices will come with a new edition of Windows called Windows 8.1 with Bing. Windows 8.1 with Bing provides all the same great experiences that Windows 8.1 offers with the Windows 8.1 Update, and comes with Bing as the default search engine within Internet Explorer. And of course customers will be able to change that setting through the Internet Explorer menu, providing them with control over search engine settings. This new edition will be only be available preloaded on devices from our hardware partners. Some of these devices, in particular tablets, will also come with Office or a one-year subscription to Office 365.
The end result is that more people—across consumer and commercial—will have access to an even broader selection of new devices with all the awesomeness that Windows 8.1 provides, and get Office too, all at a really affordable price. Additionally, as reach expands, the opportunity for developers and their apps also increases.
