I'm not going to try to get into today's announcement in any detail...It's not my foray and there are others doing a fine job already... Just wanted to call your attention to it as, from a user POV, this strikes me as pretty cool technology.
This morning, EMC announced Atmos - Policy based information management within the cloud. Chuck has a comprehensive write-up here, 'Zilla's provided his POV and Steve Todd weighs in with thoughts. I'm no expert on the details of this announcement, but found these blogs and the video below to be quite helpful in providing a high level overview.
My interpretation - and likely simplifying to a fault - this could enable me to access my stuff anywhere - anytime - through any device. I don't need to understand the bits & bytes to know that's pretty cool.
