One analyst expects Microsoft to more closely follow the footsteps of Apple than Google here.
"Judging by how Microsoft has run the Windows Phone store, I would expect a much more rigorous [app approval] procedure [than Google]," said Al Hilwa of IDC this week. "Here, in the app approval process, Microsoft is walking the fine line to provide more openness, speed and predictability than Apple, and more control and supervision than Google."
Microsoft has not set a specific grand opening for the Windows Store, but has said it will launch the e-mart simultaneously with the release of Windows 8's first beta , which will debut some time in late February 2012.
