The last time we saw a preview of Windows 8 was during Computex back on 2nd June 2011. Yesterday at the BUILD conference, Microsoft showcased Microsoft Windows 8 Developer Preview.
The new Metro UI look awesome, hopefully this time round, Microsoft will make the UI consistent throughout the whole Windows. Microsoft has learned from their mistake and the Metro UI is now built for touch rather than mouse from the group up. It is just wrong slapping a touch UI to Windows 7, it just does not work.
