It's been a long time coming, but Windows 8 -- and its low-power tablet-only cousin Windows RT -- are finally here. With Windows 8, Microsoft is trying to propel Windows forward in this new era of mobile computing and touch-screen devices. Will the tile-based "Metro" Start screen be too confusing for consumers? Can Windows 8 tablets compete with the iPad? And what's the difference between Windows 8 and Windows RT? CIO.com assistant managing editor Shane O'Neill will be live in New York City to bring you the answers to these questions and more during the Windows 8 event.\n\tJoin us for the Windows 8 launch, Thursday, October 25, 11 AM Eastern \/ 8 AM Pacific.
