Live tiles might not be groundbreaking but MSFT research on machine learning is definitely that"Live Tiles" just reminds me of widgets on an Android phone. Around since I first had a Motorola Droid... I hardly see that as "groundbreaking".
They are miles ahead of Apple and slightly ahead of Google in that regard.
Watch out for real time translator, hyperlapse , cortana and many more interesting software's coming from machine learning division of MSFT. No one can deny AI is the future.
