Before reading this further, what did you think when you first heard of Windows 8? We would venture to say that the majority of folks out there would have thought of it to be too soon to be an operating system upgrade for notebooks and desktops, especially when Windows 7 has been doing so well in terms of sales and stability compared to its predecessor, Vista. Well, more light has been shed on the situation now with us knowing that Windows 8 is a tablet-oriented operating system, one where Microsoft hopes to parade it before the end of its fiscal year in June 2011. It will apparently rely on concepts from the “Metro” interface which has been developed for Windows Phone 7. ZDNet’s Mary Jo Foley also claimed that Microsoft recently passed an internal marking point known as “Milestone 2″ for Windows 8.
