Lets review the release of Windows
The release of Windows 8 beta version would not only provide a platform to the developers and testers throughout the world to develop and test their apps, but it will also confirm the availability of Windows store from where people could download and experience new apps.
And the good news is, all the Windows 8 store apps that will release during the release of Windows 8 beta version, will be absolutely free. Microsoft clearly stated that they would not support paid apps. So, people can use as many apps as they want during that period. It will also give a chance to the testers to download free apps at first.
Microsoft has started a contest in which developers from various countries could participate and develop apps for Windows 8. The first eight apps will be selected in the contest that will come up in the Windows store as soon as it opens.
