Besides Google Android, the tablet king Apple iPad is about to get a taut rival in Windows 8. A row of Windows 8-based tablets are to enter to the scene later this 2012. Microsoft has already previewed its ARM compatible Windows 8 and a dedicated app store called the Windows Store for it. Most analysts think that Windows 8 and Windows Store will haul up crucial threat to iOS and its App Store. Maybe, Google’s Android might not have overcome Apple iPad in number of products sold. But the open source firmware enjoys a clear edge over iPad in escalating popularity. But when it comes to Windows 8, iPad may be grounded on the fact that Microsoft’s firmware is more enterprise friendlier and innovative.
